The Nortel (Alteon) Application switch will do URL hashing using a
configurable length from 1 to 255 bytes.  It's a fairly common feature,
most LB vendors support it.

Not sure if they're any cheaper than Netscalers though.

Subject: [load balancing] URL hashing

Hey all....I think I may have asked this before, but what other hardware
LB solutions out there have layer-7 URL hash balancing ? 
Specifically, I'm wondering about ones that can be defined by a URL
length to be used for the hashing.  My experience is with Netscalers,
but I'd love to know if there are cheaper ones out there that do the
same.

example:
http://images.blah.net/abcd/wxyz/blah.jpg

where a URL hash length of 10 (the "/abcd/wxyz" )

thanks,
john
