Hi, I think I am being bitten hard by bugid 2176 (http://bugs.squid-cache.org/show_bug.cgi?id=2176) which is preventing people from uploading documents over about 50k in size. I can upload fine bypassing squid but when using squid the browser keeps popping up an authentication window and the upload fails. If the file is under about 50kbytes then the upload actually works but files over 50kbytes will fail with the authentication pop ups. I have checked request_header_max_size (made this a large number), request_body_max_size is at the default 0 and reply_body_max_size is at the default too but the problem persists. I see the following in the cache.log: 2009/12/02 11:34:24| httpAppendBody: Request not yet fully sent "POST http://..." 2009/12/02 11:34:25| httpAppendBody: Request not yet fully sent "POST http://..." The site is using IIS, they probably are using NTLM and I am not sure if they will change to basic authentication. Does anyone have any suggestions for how to work around this problem (apart from getting the other end to change the auth scheme) or how to track down the bug in the source? I am running Squid Version 2.7.STABLE6. -- Brett Lymn "Warning: The information contained in this email and any attached files is confidential to BAE Systems Australia.
