Open Socket Question

[Alex Tweedly]

Sorry I'm late replying - time zone differences can be a real nuisance 
:-)   It looks from later email that you've already figured out these 
answers - but I'll answer them for the sake of completeness for anyone 
reading the threads later.

Indeed - in your code you would do something like
   set the itemDel to ":"
   if item 1 of theIPAddress is not among the lines of 
gAllowedClientList then
        close socket theIPAddress
        exit ServerContactedByClient
    end if

No, there should be no need to do that.  Though if there is a 
possibility of multiple applications trying to accept on the same port, 
that may be different.
