Hi Barry,

If you really use only the reverse proxy feature then I think the
haproxy is the better choice due the follwoing aguments:

1.) search for

2.) 1.5) Increasing the overall processing power
3.) 3.1) Server monitoring
4.) 3.4) Limiting the number of concurrent sessions on each server

Some of this features would be also very nice in nginx ;-)

What I don't know is do you use the fcgi backend or the http backend?

One of the coolest / best feature of nginx is that he deliver the
static content as fast a possible from he disc ;-))

What I don't understand why you don't use this feature, due the fact
that, as far as I understand, you deliver ALL the content thru the
application, also the static one.

As you can see I haven't setuped a blog with wordpress.
