Apache-Weblogic 404 configuration - apache2

I've searched around for this quite a bit and found similar questions but not exactly the same, but nonetheless I apologize if this is a duplicate question.
Basically, I am trying to handle HTTP error responses (i.e. 404) with a custom error page (i.e. 404.html) when my application is down, but weblogic is still up.
I am using Apache 2.2 with the weblogic module. I have set the ErrorDocument directive for Apache as well as the ErrorPage parameter within the block.
I have also set the location within my web.xml for my application, but this question is for when the application is down.
Currently, when the app is down and weblogic is running I am getting the weblogic default 404 page. How can I force apache and/or weblogic to use my custom page?
Here is a sample of one variation of the config that I have tried.
<IfModule mod_weblogic.c>
WebLogicCluster host:port,host:port
KeepAliveEnabled ON
WLProxySSL OFF
Debug ALL
ErrorPage http://host:port/errors/errorSystem.html
</IfModule>
I can access the error page directly, but traffic is never forwarded on error.
I've also tried to set the ErrorPage to a relative url which is the ideal solution.

The explanation from apache.org do it also with samples of code:
ErrorDocument 500 http://xxx/
ErrorDocument 404 /Lame_excuses/not_found.html
ErrorDocument 401 /Subscription/how_to_subscribe.html

According to WebLogic documentation, with ErrorPage parameter, "The plug-in redirects to an error page when the back-end server returns an HTTP 503/Service Unavailable response and there are no servers for failover.".
So 404 error from WebLogic will not be redirected to our custom error page specified with ErrorPage parameter.
The workaround is to create a simple webapp and deploy it onto your WebLogic. In this webapp:
in [web.xml] Specifiy your custom error code and page mappings, e.g.:
<error-page>
<error-code>404</error-code>
<location>/errors/404.html</location>
</error-page>
in [weblogic.xml] State that your context-root is '/':
<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<context-root>/</context-root>
</weblogic-web-app>
Your need to have error pages in place such as in '/errors' folder of you webapp.
Note that the 'FMW Welcome Page Application' might have already been deployed and using '/' as context-root in your WebLogic domain. If that is the case, I believe it is safe to undeploy it or untarget it, but you are advised to raise a SR to product support asking whether it is hardful to do so.

React app SPA on S3 AWS while refreshing the page shows 404 page

I have a SPA made with React JS on a S3 Bucket and I’m using Cloud Front to work through HTTPS and with a custom domain. When I refresh the page - if I have another Route that is not the BASE_URL (for example domain.com/something), S3 sends me a 404 error.
I also tried redirecting the error page to BASE_URL but it doesn’t work, it redirects me to the Http default domain that S3 provides me and again, it gives me an 404 error page.
I don’t know if there exists an alternative way to keep the URL without any change (domain.com/page) and avoid the 404 error the way a web server (apache) handles.
If you are using CloudFront to host s3 website, the effective way to get rid of 404 on reload of non-index route like www.google.com/about or similar non / is by the following steps:
Go to your CloudFront distribution
Go to Error Pages
Create a new error page with the following params:
HTTP Error Code: 404
TTL: 0
Custom Error Response: Yes
Response Page Path: /index.html
HTTP Response Code: 200
enjoy

You have two options. Either use CloudFront error page as a catch-all that redirects to / (you mentioned you tried setting an error page but did not detail what you did. This should work). The downside is that it will respond with the HTML page for all not found paths, even for mistyped CSS paths, for example.
The other solution is to use Lambda#Edge to rewrite the origin request path. This is a more customizable solution and you can define which paths you want to redirect to the root.

request has been blocked; the content must be served over HTTPS

I'm doing application with spring security and Spring MVC in back end and Angular in front end.
My problem is that I do the logged in correctly, but the problem in logged out I implemented correctly in my localhost: http://localhost:8080 worked without problem. When I change it to https:// I get this error:
Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint ''. This request has been blocked; the content must be served over HTTPS.
I want to know how to correct that? And how to know which url blocked by https in the browser for example chrome?
This post which gives a solution to your problem: http://www.learningthegoodstuff.com/2015/08/mixed-http-error-with-spring-security.html
All the details are explained there, basically all you have to do is add this two lines to my application.properties file:
server.tomcat.remote_ip_header=x-forwarded-for
server.tomcat.protocol_header=x-forwarded-proto
I fixed by removing a forward slash from the end of a URL fixing everything.this is help me : GET request throws error after app implemented SSL: Mixed Content: This request has been blocked; the content must be served over HTTPS"
This happens when the server is using http (non secured). You can fix it by enforcing https for all resources in the backend. Check here for more details.
In #Jabir Minjibir's answer there is very good link to describe the error. As sum up, when your application works with httpS scheme you can't make visits to unsecure links which is http.
I got this error and fixed it like I wrote below:
Mixed Content: The page at 'https://stackblitz.com/' was loaded over HTTPS, but
requested an insecure XMLHttpRequest endpoint 'http://172.19.0.62:920/'.
This request has been blocked; the content must be served over HTTPS.
You can mask unsecure links with simple-https-proxy npm package. In my experience I was coding an angular sample on httpS://stackblitz.com and I was trying to connect to an Elasticsearch server which doesn't have a domain name. I needed to make it working with ssl but I couldn't modify it's scheme. Thus I installed a proxy which can work secure (httpS).
I installed the npm package:
npm i -g simple-https-proxy#latest
Then I created certificate:
simple-https-proxy --makeCerts=true
Then I ran it
simple-https-proxy --target=http://172.19.0.62:9200 --port=9201 --rewriteBodyUrls=false
In another example:

angular js path returns 404 error when https is used

Please keep in mind, I have not worked with angular JS, nor did I write the code that is causing the error.
I am getting an 404 error on this path:
https://www.helivalues.com/Su6UsWuf/bb/option/mfg/all
but not this path:
http://www.helivalues.com/Su6UsWuf/bb/option/mfg/all
It was noticed that when a user views a certain page in https, the drop down does not load options. Angular Js makes a call to the path mention above which is not an actually file but is used by a php file that based on this path, has a switch that fills in the drop down.
Any ideas on how to get the https version to work? This is on a joomla site and I do have access to the htaccess file if needed. I really just need it to work for a few months while I work on building a new site.
Thanks!
Angularjs is not the issue. Your webserver (Apache/2.2.15 (SuSE) Server at www.helivalues.com Port 443) states the file can not be found. So it looks like something is misconfigured with your apache site.

Configure Amazon S3 static site with Angular JS ui.router html5Mode(true) on page refresh

How can I configure an Amazon S3 static webpage to properly route Angular ui.router html5Mode routes? On page refresh, it will make a request for a file that doesn't exist, and angular can't handle it. In the docs, they recommend changing your URL rewrites on the server.
https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions#how-to-configure-your-server-to-work-with-html5mode
However, S3 is storage, and doesn't offer the same redirection options
I have been trying to use the built in redirection rules such as
<RoutingRules>
<RoutingRule>
<Condition>
<HttpErrorCodeReturnedEquals>404</HttpErrorCodeReturnedEquals >
</Condition>
<Redirect>
<HostName>[[ your application's domain name ]]</HostName>
<ReplaceKeyPrefixWith>#/</ReplaceKeyPrefixWith>
</Redirect>
</RoutingRule>
</RoutingRules>
However, this just leads to a redirect loop.
Any suggestions?
In the Frequently Asked Questions, they rewrite almost everything to serve the index.html page. For HTML5 fallback mode you need to use #!/ (hashbang).
You could change this:
<ReplaceKeyPrefixWith>#/</ReplaceKeyPrefixWith>
with
<ReplaceKeyPrefixWith>#!/</ReplaceKeyPrefixWith>
More details on this answer: https://stackoverflow.com/a/16877231/1733117
You may also need to configure your app for using that prefix:
angular.module(...)
...
.config(function($locationProvider) {
$locationProvider.html5Mode(true).hashPrefix('!');
})
Make sure you have the index route configured for your website. Mostly it is index.html
Remove routing rules from S3 configurations
Put a Cloudfront in front of your S3 bucket.
Configure error page rules for your Cloudfront instance.
In the error rules specify:
Http error code: 404 (and 403 or other errors as per need)
Error Caching Minimum TTL (seconds) : 0
Customize response: Yes
Response Page Path : /index.html
HTTP Response Code: 200
Basically there are 3 options, use an EC2 instance to perform the actual server rewrites to the configured HTML5 routes, or, like dnozay suggested, use the fallback mode and re-write requests to use the #! hashbang. Finally, you could just use the standard angular routes, which is the option I went with. Less hassle, and when Angular 2.0 rolls around, you can update to that.

Doesn't really address the routing issue here.
here is another option using nginx proxy_pass, it also allows you to have multiple projects in subfolders and use subdomains

DNN 5.6 friendly urls

I am using DNN 5.6.3 and needing to redirect just one url to a page
the url is http://domain.com/schmooze and it should redirect to http://domain.com/schmooze.aspx
I have in the friendly urls part in the HOST find:./schmooze. replace with:~/Default.aspx?TabId=258
But I get a 404 (not found) error - Is my friendly url wrong? am I missing something else - seems this should work in the url rewriter
Try this.
Open SiteUrls.config in the DNN root directory and put this in:
<RewriterRule>
<LookFor>(.*)/schmooze</LookFor>
<SendTo>~/schmooze.aspx</SendTo>
</RewriterRule>
You will need to make sure all IIS requests are mapped to the asp.net process. To do this, set this inside of your web.config.
<modules runAllManagedModulesForAllRequests="true">
