ISA. How to access an external FTP site that is not anonymous using Internet Explorer USUAL SYMPTOMS/ https://techomusings.wordpress.com/2011/07/25/http-502-proxy-error-the-login-request-was-denied/ ERRORS: 1) HTTP 502 Proxy Error - The login request was denied 2) Cache access was denied. 3) "Port: 21 FTP failed connection attempt user: anonymous request: Get ftp://FTPServer/." http://fixmyitsystem.com/2011/03/tmg-error-code-502-proxy-error-data-is.html (this can be seen in live logging.) Please try to pass the credentials in the URL itself as ftp://username:password@domainname.com . For example, if you are trying to access a 502 proxy site testftp.com and the username is Bryant and password is 1234$, then the URL you would need to use would become, ftp://bryant:1234$@testftp.com Issue: Web proxy normally sends anonymous authentication information to an FTP site in the first request. If the FTP site rejects and closes the connection at the first try, this error is issued. If you monitor 502 proxy error the FTP traffic (you could use live logging), you will see a log entry similar to: "Port: 21 FTP failed connection attempt user: anonymous request: Get ftp://FTPServer/."

Management Gateway I had the hardest time trying to get one particular site to work from behind a TMG 2010 proxy. The users would get. Error Code: 502 Proxy Error. The data is invalid. (13) IP Address: 84.233.1 Date: 17/03/2011 02:34:51 PM [GMT] Server: Source: web filter Thiscorrelatedwith the following log event on the TMG server. Failed Connection Attempt Log type: Web Proxy (Forward) Status: 13 The data is invalid. Rule: Source: Internal (10.36.136.250:35447) Destination: External (84.233147:80) Request: GET http://lc.com/PORTAL/TOPLEVEL.php Filter information: Req ID: 0fdbab91; Compression: client=No, server=Yes, compress rate=0% decompress rate=0% Protocol: http User: anonymous The big problem I had is that this site "worked just fine" from a direct Internet connection. I used HTTP watch to trace the connection to the site. While goign through the STREAM view I noticed the following: The page was hosted on a Red Hat Apache server. (Just because it is at the top of the header) Content Encoding was GZIP The GZIP thing got me because only the one single page was being compressed. When scrolling further down the stream data I saw something strange - after the gzip data segment (green) there was "clear text" again. (Amber) I had not seen this before. This did not look right, maybe that is what TMG was on about. I check that the server would send me an uncompressed version of the page with some TamperData request header manipulation, and thankfully it did. Then I moved onto the TMG to exclude the site form requesting compressed data. Create a computer or computer set object. Open the HTTP compression setting Add the computer object to the exceptions That finally fixed the problem loading that page. GZIP implemented correctly is a fantastic thing - Do it badly and it cause cause issues, That is why I prefer to do all my compression on a reverse proxy TMG. Just goes to show you TMG was correct in dropping non standard or compliant data. Browsers were far more forgiving, this is good for compatibility but bad for standard enforcement. So if you are getting this or a similar issue requesting data from a site, look at the site closely and see if you can spot something.
