for every page request which comes in, we need to figure out what app is serving it, and which category it belongs to
I'm still curious about the use case. I'm sure there is one, if you could just enlighten me. I already know it's 'cool'.
(eg... it is a price comparision page for a mobile phone), this information is used by other modules to determine different things.
(eg... we store info on the category tree so we know that a mobile phone category is part of electronics.
so we plug parts of the URI into a hash table and store info about it for each different category.
now.. the reason we are going with shared memory on this is that there are ~10,000 (soon to be 60,000) categories on our site,
and we also have other info we store so it blows out to be ~8M->64M of memory being used just to store this stuff
we 'could' have used a gdbm/db but I think that direct shared memory would be faster than a file based DB shoved into memory cache.
The other unique application of shared memory that we plan to do soon is having a state table stored in shared mem to implement a faster setenvIf module.

(ps.. if you can suggest other methods of doing the above, I would be greatfull for the ideas)
