[users@httpd] Force/add/append/inject HTML to documents (similar to 'Header append')
for no archive
Im sure this has been asked before, but I was unable to find a
suitable query to search the httpd-users list with:
Is it possible to have Apache 2.0.53 to append HTML information to
pages as they are being served out? Similar to 'Header append', but
for the body?
I looked at all of Add* modules on the website, and couldnt think of
anything that matches. Im not sure if mod_asis or mod_cern_meta would
help.
Or does someone know of an easy way to append
<META NAME="robots" CONTENT="noarchive">
to 100+ files?
Thanks
Birl

Interesting suggestions Nick. I do have mod_include compiled in.
Im wonder though if using:
<Directory blah>
DirectoryIndex /cgi-bin/norobots.pl
</Directory>
would be easier than a 3rd party module?
Have the PERL script do something roughly like:
print "Content-type: text/html\n\n";
my $FILE = $ENV{"REQUEST_URI"};
open $FILE or die;
while (<INPUT>)
{
if ($_ =~ /<\/head>/)
{
print "<META NAME="robots" CONTENT="noarchive">\n";
}
print $_;
}
(of course this is just psudo-code off the top of my head)
Not sure what that would do to the server load.
Hmmm ... maybe I'll just use PERL to modify to the files like you
said above.
Thanks

Thankyou for your comments Nick. I will look into the
modules you mentioned below.
This may not be relevant, but I note in the php manual,
php4 and php5 support the concept of handlers.
Is this in any way related to filters Nick?
# PHP 4
AddHandler php-script php
AddType text/html php
# PHP 5
AddHandler php5-script php
AddType text/html php

Posted by ht...@karsites.net.
If you use only one page header for all your html files, you
can then use that one instance for all of the pages on your
site by including it with something like
<?php require "../incs/page-head.php"; ?>
at the top of each html page, where the <head>...</head>
section would normally reside.
Then, you only need to make one change to the included
page-head.php file, to affect all the pages on your site.

Apache doesn't do this by itself. There are several template-ish
solutions involving mod_rewrite. There's also a 3rd-party module
called mod_layout that does the trick too.

You actually don't want to append. That stuff needs to go in the
<TITLE> section, which is at the top of the file.
