[Rabbit-dev] strange 403 response

[Romain Godefroy]

Hello,

We use Rabbit 4.9 and we have this issue:

For the same ressource, without any change to configuration, sometimes 
Rabbit return a 403, and not to all clients at the same time.

exemple with a stylesheet in access log (could be a page or another 
ressources):
...
192.168.138.251 - ocb 28/nov./2011:16:11:01 GMT "GET 
http://www.mon-ip.com/style.css HTTP/1.1" 200 1986 [0, 1402]
192.168.138.251 - ocb 28/nov./2011:16:11:01 GMT "GET 
http://www.mon-ip.com/style.css HTTP/1.1" 200 1986 [0, 1392]
192.168.138.251 - ocb 28/nov./2011:16:11:01 GMT "GET

192.168.138.251 - ocb 28/nov./2011:16:12:12 GMT "GET 
http://www.mon-ip.com/style.css HTTP/1.1" 403 272 [0, 1924]
192.168.138.251 - ocb 28/nov./2011:16:12:13 GMT "GET 
http://www.mon-ip.com/style.css HTTP/1.1" 403 272 [0, 1926]
192.168.138.251 - ocb 28/nov./2011:16:12:13 GMT "GET 
http://www.mon-ip.com/style.css HTTP/1.1" 403 272 [0, 1927]
...

We check in a network dump that the response of the web server is always 
200, even when Rabbit sent 403.

When the proxy begin to answer 403 to a client, it will continue untill 
restart for this client. After restart, it respond normaly for a moment.
I'm not able to reproduce this on demand, I can only wait for it so this 
is not easy to anderstand.

Any idea ??

Thanks a lot.
