PerlCleanupHandler and redirect

[Sean Scanlon <se...@gmail.com>]

I am having a problem with using a cleanup handler where it seems that
the CleanupHandler is blocking the client browser from a redirect

>From what i understand the cleanup handler happens after the
connection is closed.

I am using the cleanup handler to do some lengthy processing while the
user is redirected to a wait page.

i am registering the handler like so:
$r->register_cleanup('MyPackage::LongProcess');

if i have the handler return right away instead of doing any processing,
the client is redirected right away otherwise it blocks until the
handler returns
which happens after the client times out.

has anyone else experienced this kind of behavior?

any info or pointers is greatly appreciated!
Thanks,

actually, while it looks like 2.0 supports a few different forms, I think it
can only be a reference to a subroutine in 1.3

  $r->register_cleanup(\&My::Package::LongProcess::handler);

or somesuch.  at least I've never seen it used any other way in with 1.3.

but, as stas said, without a proper bug report giving the mod_perl version
and other details, there's just no way to know.

one thing that may be worth looking at is the way you are doing your
redirect - perhaps there is a difference in behavior if you are using
$r->internal_redirect() versus returning REDIRECT.

Sean, to start with always read http://perl.apache.org/bugs/ before 
sending a bug/problem report. I can't tell from your report what modperl 
generation/version you are using.

what's MyPackage::LongProcess, a package name or a subroutine? It should 
be a subroutine.
