[jbosstools-dev] Any webkit / internal browser masters around?

[Rob Stryker]

Hey all:

The internal browser view / browser editor when using WebKit (and 
Snjezana indicates other internal browser implementations as well) seems 
to be caching requests that they shouldn't.  The interesting thing here 
is that BrowserViewer  (used in both editor and view) are passing in 
"Cache-Control: no-cache" into the request, and yet the results are 
still being cached.   This seems to indicate that the underlying WebKit 
is ignoring this flag for some reason.


https://issues.jboss.org/browse/JBIDE-18685
https://bugs.eclipse.org/bugs/show_bug.cgi?id=448933

Is anyone experienced enough in the underlying APIs that can assist here 
in debugging or finding what in WebKit (or other browsers) is going 
wrong that they're ignoring this flag?  w3.org documentation indicates 
these flags should *never* be ignored:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html


14.9 Cache-Control

The Cache-Control general-header field is used to specify directives 
that MUST be obeyed by all caching mechanisms along the request/response 
chain. The directives specify behavior intended to prevent caches from 
adversely interfering with the request or response. These directives 
typically override the default caching algorithms. Cache directives are 
unidirectional in that the presence of a directive in a request does not 
imply that the same directive is to be given in the response.


This could be a  bug in webkit, or in how the internal browser is 
communicating with webkit, but I seem to be out of my area of expertise 
trying to drill down into the JNI commands and webkit proper.

Anyone have any ideas or experience in this area?
