[users@httpd] SSLSessionCache

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Folks,

I'm running a 2.0.46 server on RedHat Enterprise Linux AS3. It's the stock httpd for that distribution. It sees a lot of SSL connections and the performance has been a little less than I'd expected for a 3GHz Xeon. I'm beginning to think that the SSLSessionCache is not actually being used.

The current config line says:

SSLSessionCache shmcb:/var/cache/mod_ssl/scache(512000)

Reading through various mailing lists it seems that the best way to check the status of the session cache is to enable the server-status handler with ExtendedStatus On. When I do that on my laptop (httpd 2.2.3) I see a nice set of stats for shmcb. Great. When I do that for the 2.0.48 server box I don't see the stats. I was hoping to see the shared memory segments with ipcs but either I'm misreading or they're not there on either box. I tried setting SSLSessionCache to use dbm on the 2.0.46 box (SSLSessionCache dbm://var/cache/mod_ssl/scache(512000) ) and while it didn't complain on configtest/restart it didn't create the dbm files either (the files were created on httpd 2.2.3 laptop).
Is there any way to confirm that my cache is actually working?

Thanks,
Matt
