As we know that one of the key feature of using Web Server as reverse proxy is redirections.<\/p>\n
I have used OHS 1.x, OHS 11g, and so on configuring them as reverse proxy.<\/p>\n
So far I was under the impression that you will require modules such as mod_proxy.so, mod_proxy_connect.so, mod_proxy_http.so, mod_wl_ohs.so, mod_wl_20.so, mod_wl_22.so for performing reverse proxy always. But I was wrong!<\/p>\n
Recently when I tested the OHS 10.1.4.3 which is based on Apache 1.3, all I had is libproxy.so in the location of Oracle_Home\/Apache\/Apache\/libexec. Even the mod_proxy.c block is commented out in httpd.conf file. When I just used the ProxyPass and ProxyPassReverse syntax for specific applications, it was working fine.<\/p>\n
I also used ReWriteEngine plugin (mod_rewrite.so) for performing the reverse proxy. I found that this is not used for reverse proxy always, anyone to contradict this, please shoot a reply.<\/p>\n
If you are proxying the requests using ReWriteEngine\u00a0 then follow the below syntax.<\/p>\n
RewriteEngine On
\nRewriteRule ^\/(.*) http:\/\/destination_machine:7777\/$1 [P]<\/p>\n
This syntax will redirects all URLs to destination server (7777) . So, in my case, I had form login page in ProxyServer machine and Application deployed on destination machine. So, in that case, if I protect the application in OAM and test it, it shows page not found. This is because all requests like Login page is also routed and looked in destination machine.<\/p>\n
Even if you are using ProxyPass and ProxyPassReverse for proxy purpose, be cautious to the Context where you want exactly.<\/p>\n
For example, when I used the below syntax the flow was getting stopped while showing Login page because the Login page is residing in Proxy Machine.<\/p>\n
ProxyPass \/\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 http:\/\/destination_machine:7777\/<\/p>\n
ProxyPassReverse \/ \u00a0 \u00a0 http:\/\/destination_machine:7777\/<\/p>\n
So, when I used the below syntax which will proxy only for destination application, it has started working. I had spent almost 2 hours to troubleshoot this issue ;). So, be cautious while choosing the proxy syntaxes.<\/p>\n
ProxyPass \/application\/\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 http:\/\/destination_machine:7777\/application\/
\nProxyPassReverse \/application\/\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 http:\/\/destination_machine:7777\/application\/<\/p>\n","protected":false},"excerpt":{"rendered":"
