Re: sharing data between two different apache modules

[Atanu <atanu.das@xxxxxxxxx>]

Hmm. ProxyPass do not let one append a query string and what I want will not be achievable with mod_proxy.

The other way round is using mod_rewrite, but somehow I am not able to get the translation happening The below configuration is giving me error. Forum please advice

<Location /protected>

 AuthType ECOERP::EcoErpAuthLogin

 AuthName ECOERP

 PerlAuthenHandler ECOERP::EcoErpAuthLogin->authenticate

 PerlAuthzHandler ECOERP::EcoErpAuthLogin->authorize

 require valid-user

 RewriteEngine ON

 RewriteRule /protected http://localhost:9999 [P]

</Location>

How do I read the query string? 

I want all URL in the form http://example.com/protected to proxy to http://localhost:9999/parse.pl?username=<from the login form>&password=<from the login form>

Please help!!!

My setup is Apache 2.x and mod_perl 2.x and AuthCookie(Apache-AuthCookie-3.12). I have been able to do a cookie based authentication with a (hardcoded) user-name and password  (of course from the sample files and configurations) and on authentication success have been able to proxy the request to another URL.

The question is how do I send the username and password parameters to the proxied URL? 

My httpd.conf

PerlRequire /var/www/html/Sample/startup.pl

PerlModule Sample::AuthCookieHandler

PerlSetVar SamplePath /

PerlSetVar SampleLoginScript /login.pl

PerlSetVar AuthCookieDebug 3

<Location /protected>

 AuthType Sample::AuthCookieHandler

 AuthName Sample

 PerlAuthenHandler Sample::AuthCookieHandler->authenticate

 PerlAuthzHandler Sample::AuthCookieHandler->authorize

 require valid-user

</Location>

<FilesMatch "\.pl$">

 SetHandler perl-script

 PerlResponseHandler ModPerl::Registry

 Options +ExecCGI

 AuthType Sample::AuthCookieHandler

 AuthName Sample

</FilesMatch>

# This is the action of the login.pl script above.

<Files  LOGIN>

 AuthType Sample::AuthCookieHandler

 AuthName Sample

 SetHandler perl-script

 PerlResponseHandler Sample::AuthCookieHandler->login

</Files>

ProxyRequests Off

ProxyPass /protected http://192.168.1.3:9999

ProxyPassReverse /protected http://192.168.1.3:9999

I want to do something like

ProxyPassReverse /protected http://192.168.1.3:9999?username=<from input username>&password=<from input password>

As suggested in the thread, it could be possible using mod_rewrite, but I am not able to get the rewrite rule to work in the first place. Please help. 

Thanks,

Atanu

- The user will still type http://foo.com. This time a mod_proxy handler will display a login page. In fact this my own authentication handler written in mod_perl. It authenticates using a back end system by accepting username and password from the login page.

This is all fairly standard, and you probably don't really need mod_perl.

I want the mod_proxy to ProxyPass to the url in the following format

http://bar.com/bar.pl?sid=APACHE_SESSION&u=UserName

Since you're using mod_perl, it would be fairly painless to
append the query string in Perl.  The alternative is to use
RewriteRule with [P] in place of proxypass.
