httpd-proxy-scoreboard

[Jean-frederic Clere <jf...@gmail.com>]

Hi,

I am trying to get the slotmem persistent (because for the moment it 
didn't persist even a graceful restart).
So I have a question:
- Is there a way to have a pool in a module that will only be cleaned up 
when httpd stops?

Anyway I would like to have an option to have the slotmem persistent 
over restart of httpd or machine.
In the proxy_health_checher a part of the slot mem is configuration 
information, that part only needs to be restored from the saved 
information only if the httpd.conf has not been changed.

For the moment I will write the slot mems on disk and restore them. 
Probably that has to be configurable: like restoring always, only if 
configuration hasn't changed etc.

Any comments?

Cheers

Jean-Frederic

Not easy: once I have prevented the cleanup I have to find back the 
shared memory because the module has been unloaded and reloaded.

I suppose you should do that like its done for scoreboard,
by adding a hook to core.c

ap_hook_pre_mpm(ap_create_scoreboard, NULL, NULL, APR_HOOK_MIDDLE);
