vb.net - Getting remote file size -

-

what best way remote file size in vb.net? using code:

        dim request system.net.webrequest         dim response system.net.webresponse         dim filesize integer         request = net.webrequest.create("http://my-url.com/file.exe")         request.method = net.webrequestmethods.http.get         response = request.getresponse         filesize = response.contentlength

from time doesn't work because giving invalid file size.

putty says: 1.240.214 bytes (valid), vb.net's webrequest says: 1.246.314 bytes (invalid!)

it looks webrequest using kind of cache... there better way obtain remote file size?

how make head request, this:

dim req system.net.webrequest = system.net.httpwebrequest.create("http://my-url.com/file.exe") req.method = "head"  using resp system.net.webresponse = req.getresponse()     dim contentlength integer  if integer.tryparse(resp.headers.[get]("content-length"), contentlength)     ' use contentlength variable here      end if end using

does give same result putty?
