Thanks. apache http proxy share|improve this question asked Jul 12 '11 at 6:36 chAmi 74431122 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted The problem is that you're routing your localhost traffic through your upstream gateway proxy. The upstream gateway proxy refuses to send the traffic back, either because "localhost" has a different meaning to it, or because it's trying to prevent a security threat called "proxy bounceback." What URL are you using to access your site? Put that URL's hostname in your proxy exemption list. share|improve this answer answered Jul 12 '11 at 13:20 EricLaw 42.9k492137 That's might the reason i checked my proxy setting "Bypass proxy settings for local address" in the browser settings and it works for me.

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 little familiarity with what a 502 error means, and how http://www.chicagotech.net/msapps/isa1.htm it can be fixed, you will be back in business in little time. First, let’s take a http://www.ibm.com/support/docview.wss?uid=swg21351807 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) received an invalid response from the upstream server (implying that the internal webserver that you are publishing!). Unfortunately that is not always 502 proxy 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 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 denied the specified 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 information link on the error) and see what content type is being returned by the published server. Authorize that in your content filter. • If you are using ISA/TMG as a client proxy, and the destination server is running on a non-standard port, you can encounter this error. Create an access rule allowing the non-standard ports. • “502 Proxy Error. No data record is available. (
