Is there some limit in Java on how many HTTP GET probes you can have going at once on different threads? How many waits you can have for a response from some website out on the web? If so, what happens when you go over the limit? Do you just wait to do your send or do you abort? Can you configure this limit? What is it called? -- Roedy Green Canadian Mind Products http://mindprod.com Students who hire or con others to do their homework are as foolish as couch potatoes who hire others to go to the gym for them.

Some stores have a SOAP interface. Others I have to screenscrape. I might be probing something like 30 different stores at once. I suppose each one could have a persistent connection. -- Roedy Green Canadian Mind Products http://mindprod.com Students who hire or con others to do their homework are as foolish as couch potatoes who hire others to go to the gym for them.
