Http Status-code=502 Proxy Error Loadrunner

This server received an invalid response from an upstream server it accessed to fulfil the request. This usually does not mean that the upstream server is down 502 bad gateway meaning (no response to the gateway/proxy), but rather that the upstream server and the gateway/proxy 502 bad gateway nginx do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, it often means that one 502 bad gateway fix or both machines have been incorrectly or incompletely programmed.

trying to visit. Before analysing this problem, you should clear your browser cache completely. If you are surfing the Web and see this problem for all Web sites you try to visit, then either 1) your ISP has a major equipment failure/overload or 2) there is something wrong with your internal Internet connection e.g. your firewall is not functioning correctly. In the first case, only your ISP can help 502 police code you. In the second case, you need to fix whatever it is that is preventing you reaching the Internet. If you get this problem for only some of the Web sites you try to visit then it is likely to be a problem at those sites i.e. one of their pieces of equipment is failing/overloaded. Contact the people at those sites. Fixing 502 errors - CheckUpDown Our service monitors your site for HTTP errors like 502. Use of proxies and caching is increasing on the Web. Our CheckUpDown robot will always try to "drill through" to the real computer that actually hosts the Web site, but we do not have complete control over where our HTTP request actually ends up. If only one link in the chain of computers dealing with our HTTP request is broken, then an error such as 502 can easily occur. Please contact us (email preferred) whenever you encounter 502 errors - there is nothing you can do to sort them out. We then have to liaise with your ISP and the vendor of the Web server software so that they can review the flow of IP data traffic between various computers under their control. 502 errors in the HTTP cycle Any c

Set the "Resource Page Timeout is a Warning" Run-Time Setting to Yes/No to have this message as a warning/error, respectively Reply With Quote 01-02-2008 #2 bizzzzzare Expert Member Join Date Oct 2007 Answers 375 Re: load runner error message Hi Dolphina, The reason for failure is because the time alloted for downloading Non-resources exceeds 120 secs. Go to the runtime settings of the 502 bad gateway scripts being used. Naviagte to Preferences and select Options button indicated against Set Advanced options. You would find a "Step Download timeout(sec)" value. Increment that to 10000. Also increment the HTTP - request connect timeout and HTTP - request receive timeout options to 999. let me know if this reduces the failures. Also, when you say status as failed - Are your virtual users failing or whether only Error messages are displayed ? Cheers....

Because in controller always you have to enable Replay think time. Reply With Quote 06-10-2008 #6 rpsingh46 Junior Member Join Da
by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. When / Why: The request in the script may be badly formatted. The best thing to do is check if the request has any parameters that you have edited, of so check them by debugging. HTTP 401 Unauthorised Officially: The request requires user authentication. The response MUST include a WWW-Authenticate header field (section 14.47) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity might include relevant diagnostic information. HTTP access authentication is explained in "HTTP Authentication: Basic and Digest Access Authentication" When / Why: Typically when load testing many users are generated from the same machine. In a Microsoft example the browser can use the current Windows logon credentials as credentials for the web site using NTLM. Therefore if the login is different as does not have the same authorisation as the original login (from the recording phase) during the execution the server may deny access with 401. In the script you should use: SetAuthentication(UserNameVariable,PasswordVariable,DomainVariable); HTTP 403 Forbidden Officially: The server understood the request, but is refusing to fulfill it. Authorization will not help and the request SHOULD NOT be repeated. If the request method was not HEAD and the server wishes to make public why the request has not been fulfilled, it SHOULD describe the reason for the refusal in the entity. If the server does not wish to make this information available to the client, the status code 404 (Not Found) can be used instead. When / Why: If you do not see the error when manually browsing but do see it when runnin
