[mp2] Perl Auth Handlers and mod_proxy : losing querystring on remote server (BUG?)

httpd.conf :

------------------------------------------------------------------------------

PerlModule Apache2::AuthConst

<VirtualHost *:80>
ServerAdmin suppressed
ServerName www.domain.tld
ProxyPreserveHost On
ProxyPass / http://10.0.0.100/
ProxyPassReverse / http://10.0.0.100/

CustomLog /www/doma.tld/logs/access_log combined
ErrorLog /www/doma.tld/logs/error_log

<LocationMatch /(?i)protected/>
PerlAuthenHandler Apache2::Const::OK

Require foobar
</LocationMatch>

</VirtualHost>

------------------------------------------------------------------------------

Normaly, Apache should allow connection to the remote application server for all request without calling the PerlHandler if the path is not part of /protected.

But when a page in http://www.domain.tld/protected/ is called, the PerlAuthenHandler is called in order to check the Authentication.

For now, my module just returns standard Apache2::Const::OK value, which result in allowing Apache to proxy the request to the remote application server.

This is correctly performed (anybody can test to confirm or not) ...

the problem comes when a protected page is called with a querystring : http://www.domain.tld/protected/test.php?test=true or http://www.domain.tld/protected/test.aspx?test=true

the remote application server receives the request, but with no querystring !!! it is removed after the call to the PerlAuthenHandler.

If I create some more "complex" handler to log the request (URI + QueryString) ... I can see the querystring in the Handler, but not in the remote application server.

Just by deactivating the call to the Handler (by commenting out the Require foobar line) ... the querystring is correctly received by the remote application server.

Does anybody already face this problem ???

Best regards

Sylvain
