thanks for reply, I read 5 times your post, but I don't know what I should change in my script. I'm scripting in perl around 6 months, so I am not so good in debugging. Also I thought about that, it is not possible what I want in LWP::Parallel, maybe better is use more processes, but I 'm not sure. I thought LWP:P will be easier to use (I used it without no problems with the same UA). So, if you please could write me, what I should change in my code. Thanks.
