Apache反向代理内容长度

Question

All,

I almost successfully implemented a parser on Apache/2.2.15, see part of my virtual host config included.

Problem I still encounter is when is perform a get to the two urls included

"GET /html/js/everything.jsp?browserId=ie&themeId=newTangoModuleTheme_WAR_newTangoModuleTheme&colorSchemeId=01&minifierType=js&minifierBundleId=javascript.everything.files&languageId=fr_FR&b=6120&t=1364288620000 HTTP/1.1" 200 1001584

"GET /html/js/everything.jsp?browserId=ie&themeId=classic&colorSchemeId=01&minifierType=js&minifierBundleId=javascript.everything.files&languageId=fr_FR&b=6120&t=1364288620000 HTTP/1.1" 200 1001584

I always receive a conten-length mismatch of two bytes, response header indicates 1001582 but server returns 1001584, as a consequence page is not loaded properly.

All information is more then welcome.

FYI- other js and css pages are rendered correctly only the two jsp pages provide problems !!!

Answer 1

I was having some issues with the Content-Length header being incorrectly set when ProxyHTMLEnable On was set. What corrected the problem for me was including proxy-html at an appropriate point the output filter list. In my case I was using some other filters you may or may not be using, and the line in the Apache configuration file was:

SetOutputFilter INFLATE;proxy-html;SUBSTITUTE;DEFLATE
