Summary

0001460: IE6 not responding to http 304 message properly

Description

We are running into a problem with ie6 and ie7 not responding properly to http 304 message from Resin Applications. If ie6/7 sends a If-Modified-Since header in a request for a static file like a .gif file the browser will not load the file from it's cache.

Is there a way to have resin not respond to If-Modified-Since headers?

This is happening on all of our servers, production and development.

This problem doesn't exist under Fire Fox, and if I proxy the IE6 thru WebScarab to see what is happening the problem goes away.

Thanks,

Evan

Additional Information

The web servers are Windows 2003 Enterprise. IIS6 and Resin Pro 3.0.21

(0001587) ve6eei 11-15-06 14:59 edited on: 11-15-06 15:00	I just found that if you set IE6 to use http 1.0 instead of Http 1.1 the problem goes away as well. The only thing I can see different is HTTP 1.0 doesn't support chunked encoding. I can't tell is the problem is a bad header from the server, or a cache bug in IE. --Evan

(0001588) ve6eei 11-16-06 09:33	I've narrowed it down some more. IE6/7 doesn't seem to like the Chunked Encoding along with the HTTP 304. I stepped back to V3.0.14 which doesn't respond with Chunked Encoding, and is well. So for now I will have to back rev to V3.0.14 until there is a work around for this problem. --Evan

(0001589) ve6eei 11-16-06 09:38	Here is an example of one that is working.
