"Do not exceed 10 half-open simultaneous connections" flag for LWP::UserAgent

rustyx5 has asked for the wisdom of the Perl Monks concerning the following question:

Hi all :)
I'm trying to maximize performance of LWP::UserAgent (simple web page download module), and I would like to avoid exceeding Windows limitation of maximum 10 half-open connections (Event 4226). One way is to have just 10 simultaneous downloads, but its too restrictive, I'm sure there is a smarter way :)
TIA
Rusty

You will probably have even more trouble trying to run this on Vista Home, which is limited to 2 connections. You could try to fix the problem by downloading the patch recommended for tcpip.sys.

I assume you are using this for a bot. Why not set up a loop that accepts the limit, but monitors when a download is finished, closes that Agent, then does another, etc.? You would still face the limit at any given time, but could could sset it up to contually execute...	[reply]

No, this is sort of a web crawler, so I initiate all my connections myself. As I said before, one real easy solution is to only have 10 at any given time, but in reality I can have more, just not more than 10 in the "connecting" state at any given time. Damn it, I should probably get a normal O/S :-)	[reply]
