RE: Tomcat 5.5.17 has max 40 KB / sec
Hi
I know, reasking the same question if there was no answer, is no good style.
However I had problems using apache-lists earlier and I don't know wether my
mail made it to the list.
So could anyone please respond, that the mail itself made it?
(Solutions to my problem are welcome as well :D )
