A simple tester

I need a script that works the way illustrated below... Working with two text files. - The first file has lines like: 00002|9658 00022|7748 00885|0059 (...About 100 lines like these) The second file has lines like: 102030 000000 000566 122211 (...About 500 lines like these) - Accessing the url '[login to view URL]', get the cookies, which are 2. Now using that cookies POST 'A' 'B' 'C' parameters to '[login to view URL]' ------ Parameters 'A' and 'B' are found in the first file 00002|9658 The '00002' is the parameter 'A' and '9658' the 'B' The 'C' parameter is found in the second file. ------ What I need is to test each line of the first file with all lines from the second file - Searching for '/LINE/MAGIC/' in the html response of the POST If it finds the '/LINE/MAGIC/' then save in the file '[login to view URL]' the parameters that were used to find it, like '00002|9658|102030'. Now the script should skip to the next line in the first file because already found the right parameter 'C'... ------ *** I need it done ASAP ||| *** The script MUST be multi thread (testing several lines at once)
