Do you have any special configurations with the HTTP Filter? Can you tell us more about the Firewall rule which should allow this traffic? If you have a look into the TMG monitoring do you see the right rule matched? Are you using web chaining?regards Marc Grote aka Jens Baier - www.it-training-grote.de - www.forefront-tmg.de - www.nt-faq.de Saturday, December 04, 2010 8:52 AM Reply | Quote 0 Sign in to vote Getting the same error here when trying to open my.ebay.de/ws/ebayISAPI.dll?MyEbay&gbh=1&CurrentPage=MyeBaySummary&ssPageName=STRK:ME:LNLK:MESUMX Any suggestions?

502 Proxy Error Web Service
Filter information: Req ID: 0fdbab91; Compression: client=No, server=Yes, compress rate=0% decompress rate=0% Protocol: http User: anonymous Cause This error occurs when the destination Web Server is using Chunked Encoding but it https://social.technet.microsoft.com/Forums/forefront/en-US/35156df0-9e1c-431b-b3cc-9da781f8ddfc/getting-a-data-is-invalid-13-error?forum=Forefrontedgegeneral is not passing the correct TransferEnconding header. When researching about this problem I found a great post from my friend Yuri Diógenes that explains why this problem happens: According to RFC if a server is using chunked encoding it must set the Transfer-Encoding header to "chunked". In order to compress the content we need to accumulate all the chucks and then compress. When http://www.fastvue.co/tmgreporter/blog/how-to-solve-13-the-data-is-invalid-error-in-forefront-tmg it works, TMG knows that all that content is part of the same HTTP request since it says in the HTTP Response Header; therefore it waits for the entire content, compress and send it back to the client. On the failing server we receive the first answer that doesn’t say that the content is chucked and right after that we receive other chucks, since HTTP Compression is enabled it fails to reassemble all the content since it doesn’t know that they belong to the same content." - Yuri Diógenes at: http://blogs.technet.com/b/yuridiogenes/archive/2010/12/22/3292163.aspx Solution If possible, the best way to solve it is by asking the web site administrator to change the "TransferEncoding header" parameter on the web server to "chunked". See How to enable chunked transfer encoding with IIS. Workaround If you cannot wait for the website administrator to change this, you can workaround the problem by disabling HTTP Compression for the destination site. Disabling HTTP Compression altogether will cause higher bandwidth consumption and may cause other kinds of Internet access errors, so the better solution is to ke

How do i diagnose the issue and resolve it. i posted this to the technet forums - i have gotten nothing, but they asked some questions about filters and policies - my reponse is below if it helps. i checked system | web filters | http filter and saw nothing (is there someplace else i should check) the rule allows the Teachers AD group access to all ports from internal to external, all content type, anytime, with malware inspection. the person trying to access this said it was working until a few weeks ago. i will check to see if i made any changes, but i rarely touch this system. were there any ms updates that might have affected it? a number of other people, on the technet forum, also found this same issue. any thoughts? thanks bj Post #: 1 Featured Links* RE: getting a data is invalid (13) error - 9.Dec.2010 11:33:03 AM IanC Posts: 338 Joined: 11.Jul.2007 From: UK Status: offline Hi, It works fine for me from behind TMG.
