mod_perl 2 supports output filtering, which could provide a streamlined
way of doing what Apache::Filter does fairly trivially AFAIK. But you'd

See the docs. What I am trying to do is to add a footer to the _html_ output by perl scripts running under perl_run. After delving into the camel book, I found I could try "stacked handler pipelining". I need to find out first what content type the script output is, and if it is html, the footer will be added. I'll give the idea a go now. Thanks for the replies. Regards, Jie

Are you using standard CGI scripts under Apache::Registry? Or have you written your app as handlers? If you've written your app as a handler, then If you're going to use Multiple handlers that each contribute content to the final document (i.e. first hander processes the request and the second adds header and footer info), you should check out Apache::Filter.

I'd also recommend *not* naming your headers/footers with the same extension as your files being sandwiched.

Re: Apache::Sandwich and DirectoryIndex
Clint, That is because the Sandwich module only works against html extention files, or shtml if you do the Files directive. You need to modify the module to assume the Diretory Index of your choice.

What shows up in your error logs? Did you read the section in the Apache::Sandwich docs about sandwiching mod_perl programs? If you are trying to sandwich plain old CGI's (which it doesn't seem like) then you can set SandwichHandler to cgi-handler and let it do the work. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D.Khera Communications, Inc.

That's incorrect, the standard does indeed require the HEAD section to preceed the BODY. In http://www.w3.org/TR/REC-html40/struct/global.html#h-7.3 an HTML document is defined by the following DTD snippet: Refering to http://www.w3.org/TR/REC-html40/intro/sgmltut.html#h-3.3.3 the comma between "HEAD" and "BODY" indicates that "both A and B occur, in that order".

According to the HTML 4.0 recommendation, "Every HTML document must have a TITLE element in the HEAD section." Further, the TITLE element is required. Every document must have exactly one TITLE element. http://www.w3.org/TR/REC-html40/struct/global.html#h-7.4.2 What the HTML spec does not require is for the HEAD section to come first. So if you must include the HEAD section at the end of the document, that would be fine. Experiment to ensure that this does not break user agents. -jwb -- Jeffrey W.

Re: Apache::Sandwich and SSI problems
Hi, Thank you very much for your response. I've changed my configs, so that the sandwich will work only on .html file, and set them not to be SSI parse by default. Still, the header file, which has .shtml extension is not parsed. My sandwich version : 2.2 the httpd.conf details : # # To use server-parsed HTML files # AddType text/html .shtml AddHandler server-parsed .shtml # AddHandler server-parsed .html . # shayman - enable sandwich module # for all files which ends with .html SetHandler perl-script PerlHandler Apache::Sandwich # use these documents as header and footer PerlSetVar HEADER /.includes/header.shtml PerlSetVar FOOTER /.includes/footer.shtml # parse ssi after sandwiching the page PerlSetVar SandwichHandler server-parsed # Options Includes # shayman - it doesn't seem to work The header.shtml file is located in a directory which is allowed for including (Option Includes). What else should I check ? Thanks in advance. Shay.

You're forcing all your documents to be sandwiched, including your header files. It seems you expect your .shtml and .html files to go through the sandwich handler *and* be left along when pulled through as the actual header/footer. This cannot work.

Sounds plausible. I never really put any thought into it, though. I
just punted and manually sandwich my programs that need "POST" with a
function like this:
# insert header/footer parts for *.perl programs (like Sandwich module would)
# MUST RUN UNDER mod_perl ENVIRONMENT.
#
# $which is one of "HEADER" or "FOOTER".
# Use PerlSetVar in httpd.conf to set these values.
sub insert_document_parts ($) {
my ($which) = @_;
my $r = Apache->request;
my(@parts) = split /\s+/, $r->dir_config($which);
for my $uri (@parts) {
#warn "inserting $uri " . $r->method() . "\n";
my $status = Apache::Include->virtual($uri, $r) if $uri;
#bail if we fail!
return $status unless $status == DOCUMENT_FOLLOWS;
}
return 0;
}
Then in the program, I call insert_document_parts("HEADER") at the
top, and insert_document_parts("FOOTER") at the bottom. One day I
might actually stick this function into Sandwich.pm, as it is
basically stolen from there anyhow.
