LWP Problem

Hi,could anyone help me?
I found a problem when I visit my website,The website will show me like
this:
 Software error:

Can't locate auto/LWP/UserAgent/cookie_jar.al in @INC (@INC contains:

For help, please send mail to the webmaster ([email protected]), giving
this error message and the time and date of the error.

And when I remove the floder LWP in EZXAP_NET,everything is ok.But I
don't konw why.I think the program use the default LWP package in this
machine.

My question is what is cookie_jar.al?Where and When used this file?Is
this a *temporarily* file?I run find in root directory,but can not
find this file.It's so puzzled for me.Could anyone kindly answer this
quesion,Thanks a lot.With Best wishes.
