I'm using cloudControl to develop and deploy a complex web app for mobile devices using Sencha Touch. Even when minified and trimmed of all the fat, both the CSS and the application JS weigh in at about 250KB each. I'd like to reduce this significantly (especially since it has to load quickly over sketchy mobile connections). Does anyone know if cloudControl offers gzip compression as an add-on? If not, can anyone recommend a PHP-based cloud host that does offer compression?
Gzip is enabled by default. And used if the Accept-Encoding header in the request is set accordingly.

You can always configure it to your needs using a .htaccess file. See the mod_deflate documentation for more details.

In order to resume an interrupted upload to Google Drive, we have implemented status requests to Google's API following this guide.
https://developers.google.com/drive/v3/web/resumable-upload#resume-upload
Request:
PUT
https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=UPLOAD_ID HTTP/1.1
Content-Length: 0
Content-Range: bytes */*
It works perfectly in most of the cases. However, the following error occurs occasionally and even retries of the same call result in the same erroneous response.
Response:
HTTP 400: "Failed to parse Content-Range header."
We are using the google.appengine.api.urlfetch Python library to make this request in our Python App Engine backend.
Any ideas?
EDIT:
I could replicate this issue using cURL
curl -X PUT 'https://www.googleapis.com/upload/drive/v3/files?uploadType=resumable&upload_id=UPLOAD_ID' -H 'Content-Length: 0' -vvvv -H 'Content-Range: bytes */*'

I'm trying to make a XHR request from my AngularJS instance running on port :8080 to my Structr instance running on port :8082
Thing is, Structr doesn't seem to accept OPTIONS requests on port:8080
Here is the Request header :
OPTIONS /structr/rest/issues HTTP/1.1
Host: localhost:8082
Connection: keep-alive
Cache-Control: max-age=0
Access-Control-Request-Method: GET
Origin: http://localhost:8080
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.94 Safari/537.36

Accept-Encoding: gzip,deflate,sdch
Accept-Language: fr-FR,fr;q=0.8,en-US;q=0.6,en;q=0.4,nl;q=0.2
Here is the Response headers from the server:
Access-Control-Allow-Headers:Content-Type
Access-Control-Allow-Methods:GET,PUT,POST
Access-Control-Allow-Origin:http://localhost:8080
Content-Length:44
Content-Type:application/json; charset=utf-8

The most interesting part IMHO is
Access-Control-Allow-Methods:GET,PUT,POST
I have to say that my understanding of java and HTTP Requests is really sparse so I don't really feel like digging in the source code...
Or maybe it's a simple Angular thing everyone knows but me...
Thanks to Axel Morgner the answer is :
There are two ways to solve it:
1: Let Structr serve also the AngularJS code.
2: Configure the REST > endpoint to accept OPTIONS using a ResourceAccess flag, see docs.structr.org/rest-user-guide#Securing > REST Endpoints.
Beware that when you create a Schema, structr automatically creates new resourceAccess nodes for the new possibles actions.
I've read that Chrome keeps asking for the favicon in each page it visits (link), and if it doesn't find it (404 Not found) then Chrome enters in a infinite loop.
I'm afraid that is happening to my app, although it works fine with Firefox or Safari. I haven't found a way to prevent this after go through all the forums I could find.
The http headers before the problematic request is:

If you refresh the page, the app comes out from the loop.
My Java app's url is http://glinksapp.appspot.com and is hosted in Google App Engine. It is a drive app to open link files (webloc, url...) directly in Google Drive (something not provided by Google by default).
The question is: how to avoid entering in the 404 'Not found' loop when the app tries to reach 'drive.google.com/favicon.ico'?
Thx in advance.
Chrome and other browsers automatically request the favicon, but they don't enter an infinite loop when they get a 404 (which happens on a lot of sites, so that would be a gigantic problem). The link you posted says that Chrome on Android may request the apple-touch-icon files as well, but that's okay.
The HTTP 404 response you've pasted into your question looks totally fine. Your 302 redirect also looks fine. So I suspect the problem you're experiencing is something else, not related to the favicon.
This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet.

I am developing an application with appengine 1.7.0 (python) and I am trying to add custom headers to static directories, via app.yaml, in this way:
- url: /js
static_dir: static/js
http_headers:
X-Test-Http-Headers: yo
The problem is that the http header is not being set, even after restarting the application.
Any suggestions?
EDIT:
it does not work either in development nor in production environments
EDIT 2:
debugging with Charles, the returned headers are these:
HTTP/1.1 200 OK
ETag: "f_-W8g"
Date: Fri, 17 Aug 2012 09:40:10 GMT

Content-Type: application/x-javascript
Content-Encoding: gzip
Server: Google Frontend
Content-Length: 8876
EDIT 3:
I found the problem. I changed the version and therefore the online version was not the deployed one. Restoring the version number made the deployed version available online, and therefore the headers were added:
HTTP/1.1 200 OK
X-Test-Http-Headers: yo

I'm having problems getting SharePoint 2010/IIS 7.5 to respect byte-range requests. I'm developing a SharePoint 2010 Web Part using Silverlight, and am trying to retrieve part of a document stored inside SharePoint.
When I request a byte range of a file in SharePoint, the server responds with the entire file. However, if I request the same byte range from a file sitting on an Apache server, everything works as expected. Below are the http headers observed with Fiddler.
Any help would be really appreciated! Thanks.

The problem is that SharePoint caching is off be default, and needs to be turned on to enable byte-range requests. See Disk-Based Caching for Binary Large Objects.
Note http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35.2:
"A server MAY ignore the Range header."
Thus whenever you are using a Range header you must be able to handle a 200 response. The fact that your server doesn't appear to support range serving is unfortunate, but conformant.
