Question

Hi,

I am trying to find the files from the URL path folders.that URL may be any website. for example

Input: http://www.dreamincode.net/forums/topic/77912-ftp-download-delete/

First need to parse that URL and check it out,is there any log files or document files are there within that folder. That URL is not belongs to local path, it may third party site like www.google.com/ or something else.

In our example, that folder may forums , topic and 77912-ftp-download-delete

*.log or *.doc like that..
