Hi
First of all, sorry for my english.
I'd like to limit the numbers of concurrent esthabilished connections from my local LAN per host to internet.
Avoid to "advantage" of accelerated or segmented downloading.
The --limit match is not exactly good for me, because it is matching only number of connection per time base. And so, the concurrent conections can be grow endless.
Thanks for you help, Best regards
Tom
