me thinks that PerlOptions +GlobalRequest should be inside your Directory or Location section. http://perl.apache.org/docs/2.0/user/config/config.html#mod_perl_Directives_Argument_Types_and_Allowed_Location On 9/19/07, antoine7 [EMAIL PROTECTED] wrote: Hello, I'm new to mod perl, I've setup an apache2 / MP2 on an linux debian etch server.

I've just test, changing the directive to a Directory section in apache conf, but I've always the same error. -- View this message in context: http://www.nabble.com/Perl-section-and-request-object-tf4479522.html#a12774905 Sent from the mod_perl - General mailing list archive at Nabble.com.
mod_perl - Intercepting an external Redirect
Hi. I am new to mod_perl apache2 api and hope you can help me a little bit. I've got following scenario: A incoming request A is rewritten by apaches rewrite modul to be served by mod_proxy_ajp - which is connected to a tomcat. The servlet there produce the response and this one will passed back to the client. In my case i need to intercept these response from mod_proxy and check if the response is a redirect, code3xx and the url got some prefix, say /extern. In this case i want to do a $r-internal_redirect which than would be handled again by the rewrite modul, which does a proxy request to another server X, which delivers the content. So in short, i need to analyze the response of mod_proxy and if it matches some criteria, i want to do a internal redirect and serve some content under the requested url. The client should not see the external redirect the servlet triggers. I hope i can do this with a ResponseHandler, but as i am new to this stuff, i don't know if this is the right way. Using the Handler and telling the rewritemodul to do the proxyrequest does result in the answer of the proxy modul, my handler seems to be ignored. Does someone got this scenario already? How can it be handled best? Any hints are welcome. thx Torsten smime.p7s Description: S/MIME cryptographic signature

Has anyone got an idea ? $r is a request object. It only exists when you're processing a request, so you can't use it during startup as there's no active request at that point. What is it you are trying to do?

Hey there What replacement do I have for Apache::GD to work on mod_perl 2 ? Thanks.
RE: Newbie - Samples or Tutorials
Thanks and I have alreday seen these documentations. But actually I am looking for few simple materials (tutorials) which will help my team to learn mod_perl tricks and enable them to build simple application to start with. Are there any simple sample mod_perl based applications available on the net? Any info on performace changes due to the use of mod_perl etc. Appreciate your help in this regard.

Thx for this hint.
Reading the filters.pod and looking at the examples i'll still got a problem.
I've configured mod_proxy to deliver content from server otherhost (simulates
the tomcat) and otherhost2 (which should deliver the content in special cases
but be hidden from the user).
RewriteEngine on
RewriteRule ^/time/(.*)$ http://otherhost.local/$1 [P,L]
RewriteRule ^/extern/(.*)$ http://otherhost2.local/$1 [P,L]
PerlModule MyApache2::FilterRequestFoo
Location /time
SetHandler modperl
PerlOutputFilterHandler MyApache2::FilterRequestFoo::Filter
/Location
The module does nothing special yet, as i want to see if it gets called on
redirects (if this is done i can do the logic stuff when to deliver original
content or when to do a internal_redirect to deliver content from otherhost2.
sub Filter {
my ($f, $bb) = @_;
my $r=$f-r;
warn Called Filter;
$r-internal_redirect(/extern/hidden_document);
return Apache2::Const::OK;
}
If i request /time/XYZ the filter get called and the internal_redirect is
done, i get the content of otherhost2 under the original request put
on otherhost.
Now i configured the otherhost to do a permanent redirect when /time/blog is
requested.
If i request this uri, the redirect is done like configured there - my filter
does not get called.
Did i miss something?

I've an SVN server on the same machine, at each commit the svn server update the changes to a local directory /www with this structure /www/www.domain1.com.lan/trunk /www/www.domain1.com.lan/tags/001 /www/www.domain1.com.lan/tags/002 ... /www/www.domain1.com.lan/branches/001 ... /www/www.subdomain.domain2.com.lan/trunk etc so I will have apache that point dynamicly to trunk / each tags / each branches of each domain ... we have a lot of search engine optimisation on our websites, that restrict us, if a website is on a / of the production webserver it has to be too on the dev server.

RFC: Apache2::Filter::Minifier::JavaScript
I've been working on some projects needing JS minification recently and wanted to ping others and find out if anyone else would find it useful to have a mod_perl2 filter that auto-minified your JS (using JavaScript::Minifier)... Am thinking along the lines of something that you'd set up in your Apache config like: FilesMatch \.js$ PerlOutputFilterHandler Apache2::Filter::Minifier::JavaScript PerlSetVar MINIFIER_CACHE_ROOT /path/to/your/cache/dir /FilesMatch Results would be cached to disk, so that we didn't have to re-minify the JS files on each and every request. Obviously, if the original file changes, the cached copy would be considered invalid. Seeing the above makes me wonder, though... is there a way to set up a Perl output filter for -just- specific MIME-Types? Similarly to AddOutputFilterByType, but for mod_perl handlers? Thought I'd ask and see if others would find something like this useful, or if you've got suggestions on other ways to do this. I know that I could just minify all the JS files on disk, but it'd be a whole lot simpler to just set it up as a filter and not have to worry about it. Also means that I could turn the filter off during testing and be able to work with the un-minified JS. Also thinking that an Apache2::Filter::Minifier::CSS module would be possible using CSS::Minifier; basically same thing but for CSS instead. -- Graham TerMarsch
