Get File Info from URL

[mmanda]

I am looking for a way to get file info from a URL path. Is there a way in InstallAware to acheive this? or any other suggestions

I want to build a tool that can look up file info from a Resource URL and compare it to local file, if its newer then download to update the local media, so my local media is always updated. its simple sync operation. But dont want to download if its not necessary, as i have so many files.
Any Suggestions.

Thanks
MM
