Hi,
I have an application that downloads homepages of the members of a group and searches the pages using verity to find people with particular interests.
I'll be scheduling a task to periodically download and index the pages.
My question is: Is there any way at all to check if a URL has been changed or updated (like say comparing file size or date) before downloading and saving the files.
Any help will be appreciated.
thanks,
