Hi all Im sorry before because i know that this problem already posted in this mailing list, but still I don't quite understand about the header problem and found no solutions of it. Below is the error that I got from my cache.log Previous thread about this problem says that this trouble come from the IIS, but the problem is I don't have the authorization of this webserver.. Is there any chance that I could by pass the header checking or whatever is that, so I could access the websites through my squid smoothly.. Thank u all -kodel- 2005/05/26 13:24:17| ctx: enter level 0: 'http://ls.asklearning.com/peopledimension/sa/pdfviewer.asp' 2005/05/26 13:24:17| WARNING: found two conflicting content-length headers in {Server: Microsoft-IIS/5.0 Date: Thu, 26 May 2005 06:41:24 GMT X-Powered-By: ASP.NET Connection: keep-alive Content-Disposition: inline;filename=27147_2400.pdf Content-Length: 308612 Connection: Keep-Alive Content-Length: 308630 Content-Type: application/pdf Cache-control: private } 2005/05/26 13:24:25| ctx: exit level 0 2005/05/26 13:24:25| ctx: enter level 0: 'http://ls.asklearning.com/peopledimension/sa/pdfviewer.asp' 2005/05/26 13:24:25| WARNING: found two conflicting content-length headers in {Server: Microsoft-IIS/5.0 Date: Thu, 26 May 2005 06:41:33 GMT X-Powered-By: ASP.NET Connection: keep-alive Content-Disposition: inline;filename=27147_2414.pdf Content-Length: 196598 Connection: Keep-Alive Content-Length: 196616 Content-Type: application/pdf Cache-control: private
