Hello, I am currently testing out Squid as a reverse proxy for Microsoft SharePoint services. So far everything web-based is working great. Squid is passing credentials to the back end server correctly through the use of login=PASS, pages are loading correctly, etc... There is one problem however. When a user opens up a Word document, and tries to save or save as, the save/save as window hangs for about 30 - 45 seconds, and then eventually loads a much different looking window than if not going through the reverse proxy. I can post screenshots if it will help. I finally turned on a packet sniffer to watch the traffic. I saved two sessions: one using the proxy and one going direct to the server. The only difference that I see is that the proxy isn't forwarding the WWW-Authenticate header when performing the save/save as. Going direct to the SharePoint server: GET /Shared%20Documents/Forms/AllItems.aspx HTTP/1.1 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */* Accept-Language: en-us Accept-Encoding: gzip, deflate If-Modified-Since: Tue, 17 Apr 2007 20:19:37 GMT User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; IE6SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727) Host: xxxxxxx.xx.xx.xxx.xxx:4458 Connection: Keep-Alive Cookie: WSS_KeepSessionAuthenticated=4458; MSOWebPartPage_AnonymousAccessCookie=4458 Authorization: Negotiate xxxxx HTTP/1.1 200 OK Cache-Control: private, max-age=0 Content-Length: 56495 Content-Type: text/html; charset=utf-8 Expires: Mon, 02 Apr 2007 20:19:52 GMT Last-Modified: Tue, 17 Apr 2007 20:19:52 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MicrosoftSharePointTeamServices: 12.0.0.4518 WWW-Authenticate: Negotiate xxxxx X-AspNet-Version: 2.0.50727 Set-Cookie: WSS_KeepSessionAuthenticated=4458; path=/ Set-Cookie: MSOWebPartPage_AnonymousAccessCookie=4458; expires=Tue, 17-Apr-2007 20:49:52 GMT; path=/ Set-Cookie: http%3A%2F%2Fxxxxxxx%2Exx%2Exx%2Exxx%2Exxx%3A4458%2FDiscovery=WorkspaceSiteName=xxx&WorkspaceSiteUrl=xxx&WorkspaceSiteTime=xxx; expires=Thu, 17-May-2007 20:19:52 GMT; path=/_vti_bin/Discovery.asmx Date: Tue, 17 Apr 2007 20:19:51 GMT Now through the proxy: GET /Shared%20Documents/Forms/AllItems.aspx HTTP/1.1 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/x-shockwave-flash, */* Referer: http://xx.xxx.xx.xxx:4458/default.aspx Accept-Language: en-us Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; IE6SP1; .NET CLR 1.0.3705; .NET CLR 1.1.4322; InfoPath.1; .NET CLR 2.0.50727) Host: xx.xxx.xx.xxx:4458 Connection: Keep-Alive Authorization: Negotiate xxxxx Cookie: MSOWebPartPage_AnonymousAccessCookie=4458; WSS_KeepSessionAuthenticated=4458 HTTP/1.0 200 OK Date: Tue, 17 Apr 2007 20:25:15 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET MicrosoftSharePointTeamServices: 12.0.0.4518 X-AspNet-Version: 2.0.50727 Set-Cookie: WSS_KeepSessionAuthenticated=4458; path=/ Set-Cookie: MSOWebPartPage_AnonymousAccessCookie=4458; expires=Tue, 17-Apr-2007 20:55:15 GMT; path=/ Set-Cookie: http%3A%2F%2Fxx%2Exxx%2Exx%2Exxx%3A4458%2FDiscovery=WorkspaceSiteName=xxx&WorkspaceSiteUrl=xxx&WorkspaceSiteTime=xxx; expires=Thu, 17-May-2007 20:25:15 GMT; path=/_vti_bin/Discovery.asmx Cache-Control: private, max-age=0 Expires: Mon, 02 Apr 2007 20:25:15 GMT Last-Modified: Tue, 17 Apr 2007 20:25:15 GMT Content-Type: text/html; charset=utf-8 Content-Length: 56318 X-Cache: MISS from xx.xxx.xx.xxx X-Cache-Lookup: MISS from xx.xxx.xx.xxx:80 Via: 1.0 xx.xxx.xx.xxx:80 (squid/2.6.STABLE12) Connection: keep-alive Any suggestions would be appreciated.
