Check Size of Web File Before Downloading it?

[jehugaleahsa]

Hello:

Is it possible to request the size of a file given a URL?

I would like to ignore files less than a user-specified value, but I
don't think I should have to download it first, just to find out. Any
help?

Thanks,
Travis

Well, the response *may* give you a content-length header, but it may
simply stream, in which case you cannot tell.

You can try the HEAD verb. It only retrieves the headers, which may include
the content-length. Here's some detail:
