Getting the size of a file on the web

[kappa10j]

i,

I dont want t download a file. I just want to check if it's a certain
size. In my organization, 1 of 2 images could be shown on a webpage
(and these images will oth have the same name). I've tried to get the
size by using the content header but that doesn't provide an exact
value. And downloading the file first could be too time consuming in
certain instances (this would be a quick hack fix). Is there anyway
to get the file size?

thanks,
Jordan

I've tried
BufferedInputStream in = new BufferedInputStream(new
URL(url).openStream());
FileOutputStream fos = new FileOutputStream("file");
BufferedOutputStream bout = new BufferedOutputStream(fos, 1024);
byte data[] = new byte[1024];
while(in.read(data,0,1024)>=0)
{
bout.write(data);
}
bout.close();
in.close();

return new File("C:\temp\file").length();

but it takes too long for large files.

That only works for local files though.  I've tried to specify an URL but out doesn't work.

You cannot *verify* the size of a file without having the whole file,
which requires downloading it.

If downloading the images takes a long time, that seems likely to have
an impact on the end user too …
