B.15.3. Apache::Filter—Alter the Output of Previous Handlers
Description
This section is from the "Practical mod_perl" book, by Stas Bekman and Eric Cholet. Also available from Amazon: Practical mod_perl
In the following configuration:
<Files ~ "*\.fltr">
SetHandler perl-script
PerlSetVar Filter On
PerlHandler Filter1 Filter2 Filter3
</Files>each of the handlers Filter1, Filter2, and Filter3 will make a call to $r->filter_input( ), which will return a file handle. For Filter1, the file handle points to the requested file. For Filter2, the file handle contains whatever Filter1 wrote to STDOUT. For Filter3, it contains whatever Filter2 wrote to STDOUT. The output of Filter3 goes directly to the browser.
Available from CPAN. See the module manpage for more information.
