Some of my clients are having problems accessing my Google App Engine website from typing in the URL. Despite it being written down - it's on a printed invite - as http://subdomain.domain.com (which works), people insist on putting in http://www.subdomain.domain.com
Is there some way of adding another mapping to make www.subdomain.domain.com point at subdomain.domain.com??
Help greatly appreciated.
You should be able to simply add that subdomain in Google Apps (following the instructions here). Failing that, you could use a third-party redirection service to send a 302 to your 'real' subdomain.

I have a GAE app and a custom domain registered on enom.com. The app is a static website that's configured by app.yaml.
I'm trying to use LetsEncrypt certs for ssl, so I want to have valid certs for both www.example.com and example.com. I can get the cert for www.example.com working fine.
However the problem is in my naked domain. Whenever a http request goes to http://example.com/, it gets redirected to http://www.example.com/, ok. But, if a http request goes to e.g. http://example.com/a.html, the request is still redirected to http://www.example.com/. So when LE servers come looking for their well-known acme-challenge, it fails because they see index.html.
I guess this isn't a common behavior because no one is mentioning this, not at https://code.google.com/p/googleappengine/issues/detail?id=10802, nor at https://github.com/certbot/certbot/issues/1480.
I've tried to dig into why this is happening, one error I can see is here:
If I select to overwrite, GAE says it "failed to insert mapping"
This whole project was started by another person and he claims he's not aware of example.com being assigned anywhere else. I've looked at his Google Cloud Console and it would seem that he's correct.
Maybe something of interest is that in the Domain page of admin.google.com, naked domain redirect is set up. It redirects example.com to www.example.com. I've not found a way to disable it.
On my dns registrar, I have input the four A records, four AAAA records, and a www for CNAME.
TL;DR: My LetsEncrypt acme-challenge is failing for my naked domain, help!
I started getting the same error in app_engine after I went to Google Apps account and added example.com to redirect to wwww.example.com. After I did this, in app_engine I got "is already mapped" error. And there was no way to undo the redirect in Google Apps, so my guess was that Google Apps had mapped it and so App Engine could not modify it or add it. I had to explain this to Support team, and btw Google Apps support is free to call, so contact them and then get transferred to App Engine support team.
There is no way to fix it yourself, you have to get Google Support on call and explain clearly and they can reset. I was bounced between Google Cloud and Google Suites (Apps) support teams 7 times and after 2 weeks finally resolved, each one blaming the other, until I found a guy who understood this issue and fixed it for me.
I am having a weird issue. I created an application on Google App Engine and have a Login with Facebook button on it, for which I am doing server side authentication.
I give the redirect_url, and facebook was calling the URL correctly with no issues. The session parameters that I set were being retrieved on the redirect call and everything was working fine.
Yesterday, I got a domain on godaddy and mapped it to my appspot account using google apps. Now when I click on Facebook login, I am getting two calls on the redirect uri, the first one carries the session varaibles and the session one doesn't. I am not very familiar with domain mapping and followed the steps on Google Apps.
Can anyone help me in the right direction on this.
it's a little out of date, but i documented some GAE to Facebook gotchas here:
http://javagwt.blogspot.com/2010/08/facebook-apps-on-app-engine-without-any.html
It may also help to read about naked domain mapping with godaddy, to make sure you're not getting bounced around. Even though you are mapped to your domain through google apps, you can try to put the redirect URL for facebook as yourappid.appspot.com - the redirect URL you provide, and the one in your facebook app settings must match.
My app, nimbits.com writes to facebook from GAE all of the time - the code is on github under server/facebook
https://github.com/bsautner/com.nimbits/tree/master/nimbits-tds/src/com/nimbits/server
Thanks for the answers bsautner and Michele. I finally figured out the issue. I have google ads on my website. The google ads was trying to parse the URL content and creating a second request for every request that I create. After removing the google ads, I get a single callback with session values retained. It all works now. The final output is this website - www.imagecrashers.com. I will be glad for any suggestions from the gurus here, regarding layout or api calls simplification. Thanks again to all.

Google Appengine & google Apps - mapping www.mydomain.com to my-app-id.appspot.com
I already own a custom domain for example www.onlinecourse.com, and I already have an application running on google infrastructure or google app engine with www.onlinecourse.appspot.com (just for example).
What I want is when user try to access www.onlinecourse.com, my application that is running at www.onlinecourse.appspot.com should open up without URL redirection.
I was completely fooled by this statement from google app engine.
"You can serve your app from your own domain name (such as http://www.example.com/) using Google Apps. Or, you can serve your app using a free name on the appspot.com domain. You can share your application with the world, or limit access to members of your organization."
I thought www.onlinecourse.com would completely replaces the www.onlinecourse.appspot.com
To just add a custom domain, just follow the instructions here:
http://code.google.com/appengine/articles/domains.html
And once that works, you can put a check in your code to forward anyone landing on the appspot.com domain to your domain: (example in python)
def get(self):
if self.request.host.endswith('appspot.com'):
return self.redirect('www.jaavuu.com', True)
# ... your code ...
The answer to this question should be just this url
http://code.google.com/appengine/articles/domains.html
which Amir has already pointed out.
But let me add some stuff. Firstly this is not a programming question. Second, nonetheless here's my answer.
Google uses Google Apps to manage its domains. Google Apps is something companies sign up for when they want to use gmail on mail#companydomain.com. Using Google Apps just for domain name mapping is a bit redundant, especially if you don't want any of the other stuff. But since you can disable the email, chat and other stuff, and since it is free, there is no reason , why you shouldn't sign up for Google Apps. First goto. http://www.google.com/a and sign up for the standard edition of google apps. Use a cname/meta tag/html file to verify your domain name. Once you have done that, you can add the domain name you want to use for your appspot hosted GAE app(eg. if you own the domain mydomain.com, you should map www.mydomain.com). You can redirect mydomain.com to www.domain.com using one of the n number of 301 redirect methods. I hear Google provides some IPs you can point your A names to.
Tutorial link:
http://aralbalkan.com/1466
In the tutorial, Mr. Balkan uses dynds as an example, which might not do the thing for you(it's not free). As I said before, your registrar might have enough DNS options. Else you can go for something like http://geoscaling.com (free 10 domains). The rest of the stuff should be the same.
(I guess you already have something to manage your DNS, for eg, Your domain name registrar generally gives you some amount of DNS control. Go into your domain's DNS settings and change the CNAME when required. If you can ftp to your domain's hosting, you will be able to use the meta tag or html file option to verify your domain. There are plenty of tutorials for Google Apps out there. If you are unsure, post a comment and I will expand the post)
After you are through, your www.onlinecourses.com should be what the user sees.
I'm building a application that supports different domains. A small CMS that supports different domains.
But what I can't figure out is how to redirect other domains that's outside google apps. I have a domain at google apps, that work's perfectly.
When I create a cname that points at either my appid.appspot.com or www.appsdomain.com it just goes to google.com.
What do I need to do so the other domains point to my appengine application.
..fredrik
You can't just use a cname because google needs to know how to direct the requests through their infrastructure to your app.
You should follow the instructions here: http://code.google.com/appengine/docs/domain.html to set up your name with their infrastructure so that requests to the cname get routed correctly.
Update: You do not have to move your domain to google, only inform them of the names you are going to set up cnames to point to them.
You can do that without a cname.
You need to set up a redirection mechanism of your second domain name. You can do that either by telling your registrar to redirect that url to your Google Apps url (that's how I do it with my registrar, name.com), or you could set up a small [php] script on a server you manage that would receive the queries on the second domain and issue a 301 redirect to your Google Apps domain.
EDIT: It all depends on what you want to do. If you want your app to live at both urls, then this solution will not work. I wrote this in the idea that you want the second url to redirect to your main url, if that's not what you want to do, then issuing redirects won't do the trick.
I've been fooling around with the Google App Engine for a few days and I have a little hobby application that I want to write and deploy.
However I'd like to set it up so that users are not directly accessing the app via appspot.com.
Is hosting it through Google Apps and then pointing it at my own domain the only way to go? I looked at that a little bit and it seemed like a pain to implement but maybe I'm just missing something.
My other thought was to write the app-engine piece as a more generic web-service.
Then I could have the user-facing piece be hosted anywhere, written in any language, and have it query the appspot.com url.
Anyone have any luck with the web-service approach?
The reason Google Apps is required is because you need somewhere to a) verify you own the domain (otherwise, you might point it at app engine, then I might hijack it by adding it to my account) and b) set up domain mappings (which subdomains point to which of your appengine apps).
Since this stuff already exists in Apps, it seems silly to duplicate it in AppEngine.
As has been pointed out, it doesn't cost anything, and you do not need to "move" anything to Google. You simple created a cname record with a random name to verify you own the domain, and a cname for the subdomain you wish to point at App Engine. This only takes a few minutes, and once it's done, it's done forever.
Note: If you host your site elsewhere and use webservices, you need to scale the site/frontend. If you host on app engine, you get this for free :-)
I wrote an article on my blog about redirecting *.appspot.com domains to your custom domain to keep your branding:
http://blog.dantup.com/2009/12/redirecting-requests-from-appid-appspot-com-to-a-custom-domain
To do this, I believe you need to be using Google Apps and have a custom domain setup for Google Apps. Then, you deploy your app into your Google Apps domain.
Here is google's official instructions on how to do that:
http://code.google.com/appengine/docs/domain.html
I have used this process for a couple of sites and it is easy and painless, provided you have control on the DNS records for your domain (you should).
OK, we're now at the end of 2017 and things are a lot different regarding App Engine and custom domains. It's easy now!
Go to the app engine dashboard for your app and choose Settings, then go to the Custom Domains tab. From there, choose Add custom domain.
The tricky part is that Google needs to verify that you control the domain, so they ask you to put a TXT record in the DNS for your domain. Once you do that and Google it, you become "verified" as the owner of the domain.
After that, Google will give you a bunch of A and AAAA (for IP6) records to put in your DNS. Once you've done that, you should be good to go.
It can be easily done using request.getRequestURI() method. If the URL doesn't include your domain, just redirect it to the desired URL using
resp.sendRedirect("<your domain>")
Otherwise load a error page using
request.getRequestDispatcher("<error-page>").forward(request, response);
