Re: Apache 2.4.3: Reverse Proxy: Why jsessionid is embedded into URL path of first POST after brower's cookie is cleared

[Kheng-Ee Sim <kheng_ee_sim@xxxxxxxxx>]

yes apache proxying to Tomcat 6 (backend server).

those xx.jsp scripts are all in tomcat 6.

apache and tomcat are on different systems.

followed the ideas on documentation

use proxypass and

reverseproxypass

and filter by location/locationmatch

will post the apache config tomorrow.

This looks like the cookie (https one) is set by the backend server in the response header, presumably Tomcat. Since you didn't mention what are you proxy-ing to we can just guess. Also I'll guess that the backend server receives the traffic on SSL port..

The steps taken to produce this log are :-

1) clear the cookies on the browser and restart browser.
2) Go link http://xxx.com/ddd.html (script on apache).  From the html, it is suppose to call "POST /dm/dm.jsp"
However, for strange reason on protocol.c, this first attempt after the 'cookie is cleared on the browser" it is calling POST/dm/dm.jsp;jsessionid=3404058BD1B5FB200B52FA6DA488B343 instead and failed with error 404.

3) subseqent attempts, from the html.. it will call "POST /dm/dm.jsp" successfully.


I wonder why after the browser's cookie is cleared, the first POST is embedded with jsessionid (failed)
and subsequent POST is not embedded with jessionid (successful)

Would be useful if you send the appropriate snippets of your apache config including the Proxy and VirtualHost (if any) sections and your backend server settings, if Tomcat that would be the Connector sections.
