In my environment LPH does not properly handle requests at close to same time.
What that time is I do not know exactly, mine is probably 1/2 second.
It is possible to cause it to have problems.
I have attached a screen shot showing an LPH open problem.
I agree, if there is enough time difference between the requests that LPH does not have a problem.
My CA host and CA clients are on the same local network.
I can, quite easily, replicate the problem on demand.
Perhaps it is considered unlikely that two (or more) requests for LPH will arrive at the same time on the CAHOST.
Guess that will depend upon how many users are on the CAHOST and how many are using LPH.
Perhaps, as it has been working 'fine' all these years the current process is considered satisfactory.
Perhaps this problem is because my systems are a little out of date and are not using the new TCPIP code.
Perhaps my CA host is to slow to process concurrent requests.
Attached is a screen shot I did using good old dircat that shows an error opening LPH on one of the two screens.
My testing has shown three possible results.
1) One session my receive an error opening LPH (more common when I am trying to make it error)
2) No ERRORS may be posted, two Browser pages get display, BUT BOTH are displaying the SAME file. (not common but does happen when testing from two CA Sessions on the same PC.)
3) The process works correctly, two browser pages are displayed showing different files. (only when not trying to make it error)
I am still curious about the following.
The TMP directories on my CA HOST PC and full Comet client PC are full of HTML###.HTML documents.
Is comet supposed to be clearing these out?
