[jcifs] jcifs.http.NtlmHttpFilter and POST

[Robert Baldock]

Last month I asked about the use of the jcifs NTLM filter and POST
requests.

At that time I hadn't taken account of the information on the NTLM page
about HTTP POST and protecting sub-content:

http://jcifs.samba.org/src/docs/ntlmhttpauth.html#post

And specifically the fact that you have to add a registry entry in order
for POST requests to work properly in IE.

Having made this change, the issues I have been seeing have gone away.

However, what is puzzling is that we only ever seemed to get these
errors for one URL path of a web-app. 

In particular, we have deployed this filter against an instance of
Vignette Portal and never ran into any issues with POST requests in the
/portal/console context.  However, POST requests in /portal/site didn't
work until we made this registry change.

The filter has been configured to monitor everything in the /portal
webapp so I'm wondering whether anyone has any theories as to why this
registry entry is required for one URL path but not another.

Any suggestions would be greatly appreciated.

Thanks.
