Info required
Hi In the CGI environment , After getting the request from the client , based on the request the web server will load the cgi2perl module ( may be someother name) to act as interface between perl and Webserver. The cgi2perl will get the data from perl interpreter and give back to web server. This is the way it will work in cgi environment . The cgi2perl module will use the webserver API functions to interact with webserver. Like that , i want to understand how internally mod_perl is working apart from generic explanations. Where to get all those informations. Thanks in advance. Regards K.Murugan

sharing % across requests
BlankWhat is the best way to share % across multiple requests ?
I first tried with $r-notes('name'='value') but that wasn't persistent
across requests (or maybe I was doing it wrong ?).
Then I made a system to load data from database once at process ($$) startup
and then fetch it from % (module global) on every request reloading hash if
there were any changes (add, delete, I used a file modif. date as an
indicator) and it works well but:
1) it wasn't easy for me - this was my first time doing this
2) I think it could be improved by making a module and tying hash to
that class. Now I have to call a sub to see if the hash needs to be reloaded
before using it in any sub.
The main point is that a have a small subset of variables that don't change
often but are often queried.
I'm developing in HTML::Mason. tnx.

Since he's using HTML::Mason, though, he has some examples of how to use Apache::Session, and it's pretty easy to set up. If I am remembering correctly, many of the code examples in the Mason docs assume you are using Apache::Session, and one of sample handler subroutines shows how to use it.

Re: Info required
Hi, It sounds like you want to read the source code. =) Download mod_perl (or perhaps you already have) and read the source to Apache.pm, mod_perl.pm, and so on, until you understand everything you want to. Be warned, it's not easy reading. There aren't many documents describing the internals of mod_perl, because the internals are subject to change, and the user generally shouldn't be concerned with what's going on there (unless they want to read the source).

Redirecting protected file requests to https for authentication
I have what seems to be a uncommon request. I need to write a module, or find a way, that will step in at the Authentication phase, or rather before, determine that a password is required, return a response that redirects to the https mode for the request, then allows authentication. I'm doing this so that no clear text passwords pass the network and so that any page that doesn't require authentication can still be handled using our port 80 virtualhost. basically: http://devmachine/no_authen/ - stays port 80 https://devmachine/no_authen/ - stays port 443 http://devmachine/authen/ - redirects to 443 https://devmachine/authen/ - stays port 443 and sends 401 Any ideas? I've seen a few that are close (Apache::AuthenURL, for instance), and they could be changed to do what I need, but if there isn't a way already done for specifically this, I might do it. Comments? How about a name for this, should it be necessary to right it? Thanks, JJ -- J. J.

memory leaking with closures

Re: Info required
Maybe this abstraction do the job mod_perl packages (or classes) binds with HTTP server process. Basically there is a perl interpreter loaded along with HTTP code and running in memorythe customer of mod_perl then loads additional perl code to alter the behavior of the HTTP server. The word 'alter' can be replaced with 'overload' or 'override' as well. As such, this customer would need to be aware of how the HTTP server is written. Sort of like writing an installable device driver. So now that your class (or package) is loaded and running along with the HTTP server, you can do many things, including crashing the HTTP server, just like a bad device driver. But on a good day, your package should have a handler (simply a function) that will be called (invoked) when certain events happen (an event is also a state, in which the HTTP server is). So now the thread of control is given to your package. Now you can do whatever. But whatever you do, you need to be in harmony with the rest of the HTTP cycle. And your day will end nicely, else you'll be drinking lots coffee...just like hacking with any kernel... Having said thatI recommend Writing Apache Modules with Perl and C known as the 'eagle book'. See Chapter 3, 'The Apache Module Architecture and API' and for a quick feeling, see Figure 3-3, page 60, The Request Loop. Of course I'm new to mod_perl, so if Pokymon Masters find me in fault, please train me as I want to be the best pokymon trainer...yes I got a four-year old... Good luck...

I ran PPM and had it install mod_perl from theoryx5.uwinnipeg.ca - everything seemed to run fine and in the end it asked me where to put mod_perl.so - the path I gave was c:/Program Files/Apache Group/Apache/modules - I later looked here and I could see mod_perl. I then added the following line to my httpd.conf: LoadModule perl_module modules/mod_perl.so and left everything else as it was. I now get the following when I try to start Apache: The Apache service is starting. Failed to start the Apache service. Note the errors or messages above, and press the ESC key to exit. (countdown)... I don't see any error messages that do me any good, config test returns Syntax OK and the error log shows nothing. What do I need to do? Hi, Although it appears that you've done this OK, the two most common causes of this error message is that Perl is not in your PATH environment variable when starting Apache, and that you've got a mismatch between mod_perl/Apache versions (http://theoryx5.uwinnipeg.ca/ppmpackages/mod_perl.ppd corresponds to apache_1.3.20). Are these two things OK for you? Another couple of things to check - can you load other Apache modules? And can you run ordinary cgi Perl cgi scripts (not under mod_perl)? Although it may be OK now, some time ago I had problems using mod_perl when there were spaces in the Apache directory tree names. If the above don't work, perhaps try reinstalling Apache to something like C:\Apache (you shouldn't have to reinstall mod_perl - just move mod_perl.so to the new \Apache\modules directory). best regards, randy kobes

NAME
Apache::No404Proxy - 404 Redirecting Proxy
SYNOPSIS
# in httpd.conf
PerlTransHandler Apache::No404Proxy # default uses ::Google
DESCRIPTION
Oops, 404 Not found. But wait..., there is a Google cache!
Apache::No404Proxy serves as a proxy server, which automaticaly detects
404 responses and redirects your browser to Google cache.
Set your browser's proxy setting to Apache::No404Proxy based server, and
it becomes 404 free now!
See also the section on RESRICTIONS FOR USE before you use this.
SUBCLASSING
Default cache archive is Google's one. Here is how you customize this.
* Declare your URL translator class.
* Inherit from Apache::No404Proxy.
* Define translate() method.
That's all. Here is an example of implementation, extracted from
Apache::No404Proxy::Google.
package Apache::No404Proxy::Google;
use WWW::Cache::Google;
use base qw(Apache::No404Proxy);
sub translate {
my($class, $uri) = @_;
return WWW::Cache::Google-new($uri)-as_string;
}
Define translate() method as a class method. Argument $uri is a string
that represents URI.
At last, remember to add the following line to httpd.conf:
PerlTransHandler Apache::No404Proxy::Google
RESTRICTIONS FOR USE
READ THIS before you use this proxy, especially for the default Google
implementation.
This proxy may or may not break terms of service of Google. In fact,
Google prohibits *Automatic Query* without their permissions. See
http://www.google.com/terms_of_service.html for details.
Yes, this means you are recommended to contact staff at Google,
otherwise your IP address would be blacklisted from Google :( The one
you should get contact with is Ray Sidney, whose email addy is
[EMAIL PROTECTED]. Thanks to Ray for his kindness.

Hi,
With this simple test script:
print Content-type: text/html\n\n;
my $var = 'x' x 50;
our $var = 'x' x 50;
my $sub = sub { my $sub2 = sub { $var; }; };
print Done\n;
$var does not get freed, and the process grows each request. Has anyone
seen this sort of behavior and have any ideas/workarounds (besides don't
yes. this is the documented behavior for closures. the anonymous sub
must have it's own copy of $var which happens to be 500k plus perl
overhead on each invocation.
I think the problem is that $var doesn't get freed even when $var and
$sub and $sub2 have all gone out of scope. That's a perl bug for which I
can fathom no workaround.
If any of those variables are still in scope, then of course $var can't
get freed.
