Possible addition to the guide
In the section on KeepAlives, it's probably worth adding a note about how
its beneficial to use KeepAlive if you're using SSL, because the expense of
re-establishing SSL connections is much higher than ordinary connections.

My understanding is that Ralf has had this for the last half year+ in
mod_ssl. I think it was first implemented using a dbm file for lookup
amongst the processes, and then more recently with mmap/ipc/sharedmem type
facilities. But don't quiz me on the details...

That would be server-dependent. I think stronghold does this by
default configuration. Can't say about any others.

Can someone post the details of the configuration, to make SSL server
cache those ids?
Thank you!

You just need to make sure your SSL server caches those ids.
When this was implemented in stronghold, the performance really picked
up...

Can't locate loadable object for module Mysql
Posted by Charles Galpin <cg...@lighthouse-software.com>.
I'm getting this error from some code that is attempting to connect to
mysql via DBI. The same snippet of code works fine from the command. I did
not install any of the software, but given that this works form the
command line I tend to believe that mysql and the perl DBI module are
installed and working properly. this leaves the apache / mod_perl
configuration I guess?
I can give more specifics about the versions if need be, but it's a Red
Hat Linux 6.0 box with apache_1.3.11, mod_perl-1.19 and mysql-3.22.30
This is my first experience with mod_perl, so please be gentle :)
thanks

It shouldn't be that much higher? Once the browser has gotten the symmetric
session id, it will be reused among subsequent HTTPS requests instead of doing
a key exchange all over again.
