sharing % across requests
BlankWhat is the best way to share % across multiple requests ?
I first tried with $r-notes('name'='value') but that wasn't persistent
across requests (or maybe I was doing it wrong ?).
Then I made a system to load data from database once at process ($$) startup
and then fetch it from % (module global) on every request reloading hash if
there were any changes (add, delete, I used a file modif. date as an
indicator) and it works well but:
1) it wasn't easy for me - this was my first time doing this
2) I think it could be improved by making a module and tying hash to
that class. Now I have to call a sub to see if the hash needs to be reloaded
before using it in any sub.
The main point is that a have a small subset of variables that don't change
often but are often queried.
I'm developing in HTML::Mason. tnx.

If you are looking to store a datastructure on disk (such as a hash) then you can use Storable, which allows you to serialize and deserialize your data on demand. Apache::Session has the ability to do the same, but it's not entirely intuitive if you aren't already familiar with it. there are also basic constructs like PerlSetVar and PerlAddVar, as well as Apache::Storage... again, sorry... --Geoff

Apache::Session has the ability to do the same, but it's not entirely intuitive if you aren't already familiar with it. Since he's using HTML::Mason, though, he has some examples of how to use Apache::Session, and it's pretty easy to set up. If I am remembering correctly, many of the code examples in the Mason docs assume you are using Apache::Session, and one of sample handler subroutines shows how to use it.

sorry, I think I misread the question - the verbosity threw me. No, I think you got it right. He wants to share a hash between multiple Apache children. I recommend using either MLDBM::Sync or Cache::Cache for this. - Perrin
