Subject SSI / Filter problem
Date Mon, 24 Feb 2003 18:14:48 GMT

I am having trouble with controlling the order in which asorted 
filters are acting on my pages and how Apache::ASP is acting on them. 
I would be grateful for advice.  In order, I am attempting to:

1) Run each page through Apache 2.0 external filters to write virtual 
include statements at the start of the page body:

ExtFilterDefine header mode=output intype=text/html cmd="/bin/sed 
s/<body>/\<!--#include\ virtual=\"\/inc\/header\.inc\"-->/gi" ftype=1

<Directory /home/httpd/html>
ExtFilterOptions LogStderr DebugLevel=0
SetOutputFilter header;INCLUDES

2) Execute code tucked in the body of the included header as part of 
a wholly assembled page (I want to use these variables to either turn 
on or off certain formatting):

use CGI;
my $query = new CGI;
my $Print = $query->param('Print');
my $self_url=$query->self_url;

My hope was that the virtual includes would be inserted and _then_ 
the entire assembly would be run through Apache::ASP.  Instead, 
judging from the values assigned to the variables, ASP is acting on 
the first (i.e. $self_url 
is "included://" at the time of page display).

The odd thing is that whenever the html page itself contains the 
creation of a new CGI object as a part of the page body (about half 
the pages on my site), the $self_url successfully picks up the $Print 

How can I force Apache::ASP to process the page after adding the 
includes?  I have tried assorted things already:

1) Updating the filter chain thusly:
SetOutputFilter header;INCLUDES;perl-script

2) Changing the filter so that it uses the ASP $Responce object:
ExtFilterDefine header mode=output intype=text/html cmd="/bin/sed 
In this case the resulting Perl is not executed, but rather passed to 
the browser.

2) Tweeking various parts of my ASP config:
<Files ~ (\.htm|\.inc)>
#<Files ~ (\.htm|)>
        SetHandler perl-script
        PerlHandler Apache::ASP
        PerlSetVar Debug  0
        PerlSetVar Global  .
        PerlSetVar NoState 1
        PerlSetVar BufferingOn 1
        PerlSetVar DynamicIncludes 0
#       PerlSetVar DynamicIncludes 1
        PerlSetVar CgiHeaders 0
#       PerlSetVar Filter On

If actually looking at the site would be of any help in helping me, a 
page where things seem to be working is:

An example of a page giving me frustration:

These pages will be up and down as I continue to try solving this 
issue myself.

Many thanks for both assistance and for the work put into Apache:ASP.
