Thanks to you all for this prompt responses. >>>>>>browser renders what it cans before the whole page is done downloading. I guess this is the case. I cannot do multiple reads to get incremental updates, as the post also contains input data that will get resubmitted. Is there any timeout in LWP POSTs? If none, I can just do a POST and then check results, the script can just wait whatever time it takes server to calculate. I will be reading the WWW:Mechanize man pages and check if it can solve my problem.
