you'd have to have at least a protocol/host/path separator.

http/com/ibm/www/80/somepath/somefile -> is this referring to http://ibm.com/www... or http://www.ibm.com/80...

Instead, I would imagine it should be something like:

com.ibm:http/80:/somepath

You could even do a lookup to com.ibm and ask for http SRV record to find the actual host to connect to.
