If you mean A) Must I call $r->filter_register in each handler? the answer is yes. Otherwise the bookkeeping gets off. If you mean B) Must I actually print the input handle to the output filehandle if I don't intend to change the data? the answer is 'probably'. The input needs somehow to be turned to output. Without doing this, Apache::Filter can't tell the difference between a handler that doesn't intend to change the output, and a handler that doesn't intend to send any output at all. This discussion suggests that perhaps there ought to be an easy/quick way for a handler to declare that it doesn't intend to change the output. Perhaps a method could be added to Apache::Filter for this, if it's a common need. Right now, you could do the following in the no-op handlers: $r = $r->filter_register(); my $fh = $r->filter_input; $r->send_fd($fh); (though I'm not quite sure why these exist as content handlers if they're no-ops.) ------ Ken Williams Last Bastion of Euclidity [EMAIL PROTECTED]The Math Forum
Re: ANNOUNCE: Apache::Filter 1.017
Is it required to, for instance, if you had a 4 chain handler as follows: ReadCache->Handler->WriteCache->Apache::Compress for the WriteCache handler to do: $r->filter_input() and $r->print() while <$fh> even if it doesnt need to? If I don't do that I seem to be losing all output, when I get to the Apache::Compress stage - Original Message - From: "Ken Williams" <[EMAIL PROTECTED]> To: "modperl" <[EMAIL PROTECTED]> Cc: "JR Mayberry" <[EMAIL PROTECTED]> Sent: Friday, April 06, 2001 6:02 PM Subject: ANNOUNCE: Apache::Filter 1.017 > The URL > > http://www.mathforum.com/~ken/modules/archive/Apache-Filter-1.017.tar.gz > > has entered CPAN as > > file: $CPAN/authors/id/K/KW/KWILLIAMS/Apache-Filter-1.017.tar.gz > size: 24147 bytes >md5: 304aabb626ae8694ca75e639b1981e7b > > > Changes from 1.016: > >Fixed a filehandle bug in which send_fd() would complain about a 'Bad >filehandle'.

ANNOUNCE: Apache::Filter 1.017
The URL http://www.mathforum.com/~ken/modules/archive/Apache-Filter-1.017.tar.gz has entered CPAN as file: $CPAN/authors/id/K/KW/KWILLIAMS/Apache-Filter-1.017.tar.gz size: 24147 bytes md5: 304aabb626ae8694ca75e639b1981e7b Changes from 1.016: Fixed a filehandle bug in which send_fd() would complain about a 'Bad filehandle'. Occurred most often with Apache::Compress. Added a couple of tests to properly exercise the send_fd() method. ------ Ken Williams Last Bastion of Euclidity [EMAIL PROTECTED]The Math Forum
