in reply to cookie question
If I understand your question correctly, you are creating a cookie with CGI.pm. In another transaction, some javascript is modifying that cookie. You then want to know if perl will be able to read that new value in yet another later transaction.
The answer to THAT question is yes. As long as the javascript modifies the correct cookie value, after the javascript modifies it, perl should later on be able to read back in the new value (provided, again, the correct value is specified).
