ProxyPassReverse Issue in Apache 2.2.3/CentOS, but works in Apache 2.2.14/Ubuntu [only directory redirect issue]

[Hridayesh Gupta <hridayeshiitd@xxxxxxxxx>]

I have the following rule in conf file at server.com

RewriteEngine On
RewriteRule /source(.*) http://example.com/target$1 [P]
ProxyRequests Off

ProxyPassReverse /source http://example.com/target

http://example.com/target/a.php redirects to http://example.com/target/b.php

http://example.com/target redirects to http://example.com/target/

When I visit http://server.com/source/a.php , it redirects correctly to http://server.com/source/b.php which will serve the content from http://example.com/target/b.php as defined in rewriterule, But when I visit http://server.com/source , it does not redirect to http://server.com/source/ instead it redirects to http://server.com/target/

The above worked correctly on my local machine Apache 2.2.14/Ubuntu with same setting.

I also have checked Location header using firbug while visiting http://example.com/target and http://example.com/target/a.php and in both cases Location header string is full url eg http://example.com/target/ and http://example.com/b.php

So In my understanding ProxyPassReverse is not substituting Location header correctly in Apache 2.2.4/CentOS

Please help me for this issue. Please let me for any further information.

Thank you
