Hi Scott,
Sorry I took so long to respond. I removed the forward and simply
sub-classed the home page and now I still get max recursion depth
problems but now they are down in Cheetah and usually only when someone
is requesting malicious URLs that don't exist. Since this code has

While browsing the Python Package Index I came across a module that runs
your Python program like a debugger and generates a UML graph. I
thought it was pretty nifty and might be useful for documentation.
Here's a graph of WebKit.

Hi all,
What format is the connect string for MySQLdb? It doesn't even appear to
accept a connect string as far as I can tell it thinks I'm passing in the
host name when I try. I'm using DBPool which as far as I know only uses
connect strings, not individual parameters.
Thanks,
Jeff

Ah, now it makes sense. On Cold Fusion I use a

I think
Most of our websites use sessions to store a variable like
loggedInUserID to track who is logged in. To handle the load from
advertising campaigns, I've setup two computers with Apache and Webkit
running on each. I then use round robin DNS so hopefully an individual
user will go to the same web

We actually have a hardware load balancer that is collecting dust
because I had already written oodles of cold fusion using sessions and
getting primary keys from MS SQL Server by "select max(primaryKey) + 1".
The load balancer doesn't have the option to use cookies to keep users

I'm looking at moving our high traffic site to Webware and need to
support clustering. I plan to use PostgreSQL on a dedicated server with
two or more servers running Apache/Webware. Using Sequences to generate
primary keys should handle the issue of creating unique primary keys
across servers.
My ISP rebooted my servers by accident this morning which prompted me to
get around to writing init scripts for webkit on FreeBSD 4.3.
"start" and "stop" seem to work ok but "restart" only works if there is
no load on the server since the start doesn't wait for the stop to
complete. Any ideas

I thought I sent in a bug email to the list last week but I can't find

Maybe there is already a mechanishm to do that but you could put

Hi Tom,
Here's a smaller but still complete example of using FunFormKit with
