conventional location for backend server

[Mike - EMAIL IGNORED <m_d_berger_1900@xxxxxxxxx>]

On Linux FC4 with Apache 2.0, I have constructed
a backend server for my reverse proxy.  I would
prefer not to put it in /var, to avoid confusion
with test operations on the same box.  Is there
a conventional place for this?  For example, I
notice that /srv is empty.

Thanks for your advice.
Mike.
