Problems using firewall parent

Hi all,

I have a problem with accessing web sites that are redirects to another URL
(ie. 302 Moved Temporarily). It is easiest to explain by example.

Example:

1. Client contacts local proxy, proxy goes direct to origin - everything is
fine.

2. Client contacts remote parent directly - everything is fine.

3. Client contacts local proxy, request is forwarded to parent
(never_direct allow all) - client waits (2mins +) but finally gets the page
requested.

In the above examples, this only effects URL redirects not normal
requests. The problems only occurs using MSIE and only when the request is
forwarded to a parent cache. It does not effect Netscape in any configuration.

Looking at the debug produced, the only difference between MSIE and
Netscape for the same request is:

IE:
1999/12/05 16:01:06| clientProcessMiss: 'GET http://www.hotmail.com/'
1999/12/05 16:01:08| clientSendMoreData: http://www.hotmail.com/, 233 bytes
1999/12/05 16:01:08| clientSendMoreData: FD 9 'http://www.hotmail.com/',
out.offset=0
1999/12/05 16:01:08| clientSendMoreData: Appending 0 bytes after 233 bytes
of headers
1999/12/05 16:01:08| clientWriteComplete: FD 9, sz 291, err 0, off 233, len -1

Netscape:
1999/12/05 16:02:53| clientProcessMiss: 'GET http://www.hotmail.com/'
1999/12/05 16:02:54| clientSendMoreData: http://www.hotmail.com/, 452 bytes
1999/12/05 16:02:54| clientSendMoreData: FD 9 'http://www.hotmail.com/',
out.offset=0
1999/12/05 16:02:54| clientSendMoreData: Appending 230 bytes after 222
bytes of headers
1999/12/05 16:02:54| clientWriteComplete: FD 9, sz 519, err 0, off 452, len 452
1999/12/05 16:02:54| clientWriteComplete: FD 9 transfer is DONE

Versions Used:

   MSIE NT v5.01
   Netscape 4.7
   Squid 2.2.STABLE5 and 2.3DEVEL3

   Parent caches are either NetCaches or other Squid boxes.

Can anyone else confirm this?

Graham
