Re: cgi-lib.pl
Hi there, Thanks everyone for the great information you have provided. I have taken everyones advice and installed CGI.pm with the cgi-lib compat mode on. I am still having an issue that is only associated with the mod_perl version of the web server? I have two variables at initial login $userid and $password that are populated via the cgi-lib readparse. Upon initial login the variable will contain the correct information. If i would hit refresh they double and keep going everytime i hit refresh? Ex: $user = joe | Refresh -> $user=joejoe | Refresh -> $user=joejoejoe I dont get it, i went thru my code and cleaned it up to make sure the vairable were emptied on every execution by placing: $userid = ""; $password = ""; before the data assignments. And still get the same effect? Anyone have a clue, is it CGI.pm or mod_perl, the same source does not do it on a non-mod_perl server.

Help needed with compile
Hi, I am trying to compile Apache with a bunch of modules and DSO. I cant find any documentation that covers all of this though. perl.apache.org/guide/ give lots of combination examples, but not all. I would like to build Apache 1.3.20 with mod_ssl, mod_perl, mod_php and DSO support, and for apache, --prefix=/apachessl. Can anyone give me either a site that has explicit instructions on how to do this? Or maybe an example? Thanks! Bryan

The connect header is a special proxy feature to allow a proxy to just pass through all the TCP level packets instead of opening a separate SSL client connection. But from a reverse proxy perspective, I am not sure that mod_proxy is automatically given this special header by the browser as it might if you configured IE or Netscape to use a physical proxy server.

If you compile in mod_ssl, mod_proxy can establish SSL connections to the back-end. The only thing you lose other than performance is the capability of passing a PKI certificate through the proxy (since decoding and establishing a new SSL connection would be considered a man-in-the-middle attack). When you don't care about client certificates, it really doesn't matter that the reverse proxy is in the middle because the reverse proxy has the valid server certificate that your client is pre-programmed to understand is a valid certificate (eg from Verisign). Really, the cleanest way of doing what you want is to run the SSL engine on the front-end and then proxy (convert) back the connection to the backend as HTTP. If you are using some authentication on the front-end (eg client certificates) there are modules which will allow you to take a USER_DN and pass it to the back-end server as an addition parameter (eg using mod_rewrite) or as another custom HTTP header. > Issac > > > At 03:26 PM 7/25/2001 +0200, Issac Goldstand wrote: > > >I am trying to make a back-end mod_perl/mod_ssl server.

Re: [OT] Using mod_proxy and mod_ssl to forward SSL connections
The front end server must be configured to understand SSL. Otherwise, how else can the HTTP request be pulled apart (decrypted) to understand that it has to be forwarded to the backend server. If you configure the back-end server to understand SSL, that's OK, but beware that all mod_proxy is doing is establishing one SSL connection from browser to mod_proxy and then a brand new SSL connection from mod_proxy to the backend server. 2 separate SSL sessions because SSL cannot (ie inconvenient to) be man-in-the-middled. It has some likelihood to also to be inefficient because I am not entirely sure that mod_proxy is caching the SSL client session key that it generates to connect to the back-end server as the browser normally does for the front end.

[OT] Using mod_proxy and mod_ssl to forward SSL connections
I am trying to make a back-end mod_perl/mod_ssl server. The front-end server that is currently in place is doing a great job forwarding normal requests to the back-end, but it is not forwarding SSL. Now, the front-end server does not understand SSL, itself. What I'm doing is trying to force the entire VirtualHost listening on port 443 to an IP on a private subnet on an obscure port (what I do for all the back-end servers. There are actually 3 of them doing various things). But it won't work. The strange thing is that if I go to http://mysite:443/ I get the default Apache "It Worked" page, but https://mysite/ generates an error saying that the front end cannot understand, which seems to be pointing at the fact that it's not forwarding ANYTHING to the back-end server... Stas & Eric: This situation is mentioned in your book, but in nowhere enough detail. IMHO, that segment of the book (near the end of chapter "Server Setup Strategies for the Best Performance") should be redone in better detail to explain forwarding SSL to the back-end server.

I'd rather think of it as a WebApp::Config _object class_ than a
WebApp::LoadConfig _module_ (see below).

How about the Config::Ini module from CPAN, that implements m/Win...s/
.INI format ? It's versatile and quite easy to understand even for
your newbie users. Plus it's already done and well tested, and it has
write support (comments are discarded). Here at IDEALX we use a
subclass that goes like this:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
package My::Hierarchy::Config;
use strict;
use Config::Ini;
use vars qw(@ISA); @ISA=qw(Config::Ini);
# new My::Hierarchy::Config() called with no args returns a
# config opened on the default configuration file.
sub new {
my ($class,$filename)=@_;
return $class->SUPER::new($filename or '/etc/mywebapp.conf');
}
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
And then in every script:
my $config=new My::Hierarchy::Config;
$config->get(['somesection','somekey']);
This allows for maximum flexibility: by adding code to
My::Hierarchy::Config, you can provide convenience functions to do
just about anything that suits your needs (e.g. there could be one to
export the whole config file to random variables in all packages).

Well, it depends. We find it quite useful to stay in the CGI context
for our scripts, since unit tests are much easier with CGI.pm's
debugging code. And for that reason, we choose not to specialize
mod_perl's environment more than it already is (e.g. $r et al.). We
put the above boilerplate in every script, perhaps wrapped in a
convenience function (e.g. ``use My::Hierarchy::CGI;''). But if you
intend to jump the gap and have a totally ad-hoc structure for your
Perl pages (e.g. you use HTML::Mason or something alike), then yes,
why not make $config a global variable accessible to all Perl WWW
pages ?
