All users use web proxy on port 8080 to browse the Internet from the Internal LAN. Our users can succesfully browse the Internet except when they want to access one specific web site. The web site is: http://www.dataviz.com/downloads/demo/index.html?product=RDS When they access the web http://forums.isaserver.org/ISA_Error_Code_502_Proxy_Error/m_2002046592/tm.htm site, the following ISA error is displayed: Error Code: 502 Proxy Error. The HTTP message includes an unsupported header or an unsupported combination of headers. (12156) Is there something we can do on our side to give access to the specific web site? Thank you.

502 Proxy Error Whenever an ISA or TMG server throws a 502 Proxy Error your way, you know you are probably in for a real hurdle. But with a http://www.chicagotech.net/msapps/isa1.htm little familiarity with what a 502 error means, and how it can be fixed, http://stackoverflow.com/questions/486517/error-code-502-proxy-error-the-isa-server-denied-the-specified-uniform-resourc you will be back in business in little time. First, let’s take a look at the definition of 502 HTTP response code: 502 Bad Gateway The server was acting as a gateway or proxy and received an invalid response from the upstream server. Pay close attention to what that is saying. The proxy (meaning your ISA or TMG server) isa server received an invalid response from the upstream server (implying that the internal webserver that you are publishing!). Unfortunately that is not always the case as ISA and TMG can throw that error when they are unhappy about something that a normal browser would readily accept. They can also throw one of several different kinds of 502 depending on the circumstances. Understanding is critical to a quick resolution. Don’t just stop reading at 502, check isa server 502 the rest of the response. Here is how to determine whether the problem is with your ISA/TMG, or on the internal server: 1. Open a browser on the internal network. 2. Access the URL in question. 3. If you can view the content successfully, the problem is with your ISA/TMG. If not, the problem is with your webserver. Since this post is about ISA and TMG, let’s assume you are able to view the content internally just fine, so we’ll keep discussing ISA/TMG. 4. Go to your log viewer. In ISA that is Monitoring, or in TMG that is in Logs & Reports. 5. Edit the filter to look at live logs and have the user try again, or filter on the time range to see the error. Add the “Filter by” criteria for HTTP Status Code, and set it equal to 502. 6. Run the query, and examine the results. Some of the frequent causes of ISA/TMG generating 502s are: • A 502 can be thrown by the ISA/TMG when content filtering is enabled and something in the response is being blocked. Disable content filtering and see if you are then able to access the resource. If you are, look at the header in one of the logged errors (in your log, click the more inform
