 Hi,

 I am currently working on a contract where I am setting up WordPress MU to
 run an intranet on a Windows 2003 server. HTTP connections are locked down
 and the only way to connect to the internet is via an ISA proxy server. I
 used the recommended proxy settings in wp-config.php however this did not
 work for me. I did a little digging into the WordPress core code (/wp-
 includes/http.php) and I found that the proxy code doesn't support NTLM
 authentication. I have patched my version of http.php to support NTLM and
 this now works great. I have also added an extra constant in wp-config.php
 to configure this:

 define('WP_PROXY_AUTHTYPE', 'NTLM');

 I have produced a diff of the changes I made and would like to contribute
 them as I am sure there are other people who will encounter similar
 problems. Especially in a corporate network environment.

 I have tested that NTLM proxy authentication will work using pecl_http
 (exthttp) and cURL. However I couldn't get it to work for streams, fopen
 or fsockopen. I couldn't find any documentation or forum posts of anyone
 succeding with these methods but the core developers might also want to
 take a look.

 Please let me know what you think.

 Cheers,

 Steve
