Plus,Do u seek any issue in my code?

I see some issues, but I don't know if fixing them will help you

I see you didn't use strict/warnings to cut your development time in half!

I see you don't dump in handler but do something else

I see you check the value of show_progres instead of turning it on

You use the bareword TIMEOUT for timeout

I see add your own Basic header and use/credentials -- I don't know what that will do, but that is kind of the purpose behind LWP, to do that for you

Also, WWW::Mechanize can simplify your LWP::UserAgent interaction, no need for constant status_line checks as it will die for you,
or saving the response, it keeps track of all that ( WWW::Mechanize::Cookbook, mech-dump )

WWW::Scripter is a Mechanize helper
