No! Because the persistent connection gets opened with one child, and when 
you go for the next page you have very high probabilities (unless you have a 
very poor http configuration) of caching a new child, and not the old one.

The problem comes here, just because the pconnect was done against the old 
child, and the new one doesn't know a thing about the pconnect you did 
before, so you'll allways (or almost always) an error of "wrong connection 

Hope I was clear.
