I tried that by using r->variable("mykey", "myvalue") from a Perl
handler, but the variable was unavailable in another module. It turns
out that ngx_perl_module stashes this variable under it's own ctx()
which is not directly available in another module. Unless you try
poking around r->ctx array and go look for it.

I'm really missing a way to identify other modules. It would be really
nice if modules had an id (in Apache, that is the filename) that could
be looked up by other modules.

Any tips on how to identify other modules?
