Hi all,
I am trying to setup a reverse proxy to fwd requests to another back-end
server. The back-end server actually holds a SSO application, and so for any
GET from browser, it pops up a login form, which on being submitted with
correct credentials, grants the requested page. This is from logs/access_log
(contains initial page with 302, login page, the POST action and finally the
initial page):
10.77.199.189 - - [28/Jun/2007:18:13:30 +0530] "GET /pfg/poststaticdata.html
HTTP/1.1" 302 281
10.77.199.189 - - [28/Jun/2007:18:13:30 +0530] "GET /login.html HTTP/1.1"
304 -
10.77.199.189 - - [28/Jun/2007:18:13:31 +0530] "POST /cgi-bin/printenv
HTTP/1.1" 302 294
10.77.199.189 - - [28/Jun/2007:18:13:31 +0530] "GET /pfg/poststaticdata.html
HTTP/1.1" 200 1290
Now, I have set up a reverse proxy which ultimately sends request to this
server - the login page is coming, but on clicking submit, the login page
again pops up. The following is the access log from the backend server:
10.77.199.15 - - [28/Jun/2007:17:50:13 +0530] "GET /pfg/poststaticdata.html
HTTP/1.1" 302 281
10.77.199.15 - - [28/Jun/2007:17:50:13 +0530] "GET /login.html HTTP/1.1"
304 -
10.77.199.15 - - [28/Jun/2007:17:50:17 +0530] "GET /pfg/poststaticdata.html
HTTP/1.1" 302 281
10.77.199.15 - - [28/Jun/2007:17:50:17 +0530] "GET /login.html HTTP/1.1" 200
869
There is no POST to the action page, although it does come up in a browser
based HTTP trace logs. Am I missing something here?
Also, the login.html page again pops up. Are these 2 related?
I also saw that the POST appears in the proxy server access log:
10.77.199.189 - - [28/Jun/2007:17:58:58 +0530] "POST /cgi-bin/printenv
HTTP/1.1" 302 324
This is my httpd.conf on the reverse proxy server:
<IfModule mod_proxy.c>
ProxyRequests Off
ProxyPass / http://ps2844:1880/
ProxyPassReverse / http://ps2844:1880/
ProxyPass /pfg http://ps2844:1880/pfg
ProxyPassReverse /pfg http://ps2844:1880/pfg
ProxyPass /cgi-bin http://ps2844:1880/cgi-bin
ProxyPassReverse /cgi-bin http://ps2844:1880/cgi-bin
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
</IfModule>
>From the log file of the reverse proxy, I could see that the re-direction
was happenning correctly.
If anyone can push me into looking at the correct location, that would be
great.
Thanks,
Ambarish Mitra.
