You can define a sub named CLEANUP in every Embperl page. That will be call
after the request is finish and the connection to the browser has been
closed. As the name suggest, a good place for cleaning up (like closing
database handles). But I guess that's not what you want. To get your module
called every time any Embperl is requested, use EmbperlObject, there you can
define a base page that looks like:

base.htm:

[- $obj = new whatever::module ; -]

[- $obj -> init -]

[- Execute ('*') ; # This calls the page -]

[- $obj -> term -]

in your httpd.conf

PerlSetEnv EMBPERL_OBJECT_BASE base.htm
PerlHandler HTML::EmbperlObject

of course you can do much more with EmbperlObject.

How long has CLEANUP been around? I remember asking you about END blocks a
while ago and you said you'd add it to the todo list. I really need to pay more
attention because CLEANUP will be a big help for me.

Thanks.

All right. His story checks out.

I added it somewhere in 0.2x (so about 2-3 years ago)

Oh, sorry. I don't use CLEANUP often, so looks like I had just forget to
mention it when you ask the last time.
