I have a reverse-mpaf almost working with this now, so that it works

I'm sure it's in the docs somewhere, but personal experience and 
previous posts to this list have addressed this issue.

Convert as in from POST request to GET request.

sub escaped {
my $val = shift;
$val =~ s/(\W)/sprintf("%%%.2X",ord($1))/g;
return $val;
}

my $content = join('&',map{$_."=".escaped($r->param($_))}($r->param));

my $internal_url = "/some/path/to/handler?$content";
$r->internal_redirect($internal_url);

Thanks for the info.  I realized just now (about a minute ago) that
localhost.mailermailer.com and localhost.m1e.net are different names
that point to 127.0.0.1, so the proxy front-end can do it using the
domain names, and the back-end can distinguish the names just fine.

It seems that everything concerning vhosts is set up in http_protocal.c
and that the vhost is set right after Apache has read the request from 
the client and then calling ap_update_vhost_from_headers to actually
determine the vhost. All this happens before your module gets to run.
It might be possible to create a C module that sets the Host: header 
like you want it to be and then call ap_update_vhost_from_headers.

Would it make any diference if the method, and method_number remained
POST? Does this situation occure as a result of method conversion? (I
will try that)...

Re: $r->args()

[Tom Servo]

Once you change the method to GET and put the content in with $r->args();,
it becomes GET data from the query_string.   All the POST data is lost
when you call content(), so you can no longer read it as POST data with
$r->content() again.

Performing a redirect causes posted data to be discarded.  Your goal 
should be to convert all of your posted data so that it can be passed 
via GET.

I am affraid it did not work. I have no problem reading the data in the
current handler, but right after redirect, which is also required to
read the data, I loose all the POSTED data.

So your goal is to turn a post request into a get request using an 
internal redirect.

param does not work like args, and $content in this example will 
return the number of param keys (IIRC).

I think you want

my $content = join('&',map{$_."=".$r->param($_)}($r->param));

Which should solve your problems (I think).

is postreadrequest too late to determine name vhost?

[Vivek Khera]

I've got the classic lightweight front end proxying to the mod_perl
heavyweight backend.  I use proxy_add_forward on the front end and the
PerlPostReadRequest handler to set $r->hostname and $r->remote_ip.

This all works excellently.  My question, however, is this too late
for the name-based virtual hosts to trigger?  In my mod_perl app, I
need to trigger different things based on the virtual site.  What I
want to do is this:


 ServerName www.mailermailer.com
 PerlSetVar SiteID 7
 PerlSetVar SiteName www.mailermailer.com



 ServerName m1e.net
 PerlSetVar SiteID 1
 PerlSetVar SiteName m1e.net


in the backend.

However, it seems that it always picks up the first virtual host
defined this way, regardless of what the post read request handler
sets $r->hostname to.

Is there some other trick I should try?  I'm working from home today
and don't have my Eagle book handy...

If I can't get it to work with name virtual hosts, I'll have to go to
port-based virtual hosts, which I'd prefer to avoid since I expect to
have several hundred of these eventually.

Thanks.

As well as what Rod says in another reply about this message arising
from incompatible Apache/mod_perl versions, this can also be caused
from not having the perl executable in your PATH environment variable
when starting Apache.

Re: Apache, mod_perl

[Rod Butcher]

This message has confused many people including me. It usually means that
the mod_perl binary is incompatible with your version of Apache. Most people
compile the whole lot together. Randy Kobes has kindly compiled mod_perl
binaries for recent Apache versions at
ftp://theoryx5.uwinnipeg.ca/pub/other/ppd/x86/
You can download the version of mod_perl that matches your version of Apache
and unzip it into the Apache module library. You can then look at the
compile options.
