guinness Posted May 17, 2013 Share Posted May 17, 2013 (edited) This is the first time I've come across InetGetSize returning 0, I have an example below (though sometimes it will report a size greater than 0.) Having done a bit of research on the Forum, it appears that it used to be a bug in InetGetSize, though I have a WinHttp version which returns exactly the same result as InetGetSize, so I doubt this is a bug with InetGetSize today. I'm wondering is this a flaw in the header that is sent from the server or the functions? I'm going with the server, but would like to know your thoughts too.

JohnOne Posted May 17, 2013 Share Posted May 17, 2013 (edited) I do not believe http works in the same fashion as InetGet*, and work directly on a file. I'd suggest that InetGetSize would want to query the actual size on disk which the server will not serve up for a php file. EDIT: Of course that does not satisfy the apparent erratic behaviour of both functions in your code, so I'd be wrong.

guinness Posted May 17, 2013 Author Share Posted May 17, 2013 Thanks JohnOne. I presume this is InetGetSize >> http://msdn.microsoft.com/en-us/library/windows/desktop/aa384238(v=vs.85).aspx with the query flag HTTP_QUERY_CONTENT_LENGTH.

JohnOne Posted May 17, 2013 Share Posted May 17, 2013 I'm unsure, looks more like InetGetInfo, unless they're one and the same just rolled in AutoIt.

kylomas Posted May 18, 2013 Share Posted May 18, 2013 guinness, I run into the same depending on where I am scraping. I attributted it to this Not all servers will correctly give the file size, especially when using a proxy server. from the Help file and assumed that was the problem (maybe I jumped to that conclusion too quickly?). kylomas Forum Rules Procedure for posting code "I like pigs.

If you look at the whole header you'll se that transfer-encoding is "chunked". That means the server sends data in chunks which are separated by separator and the whole transfer ends with zero size mark + double-@CRLF. Size is known in advance when Content-Length is specified as you show in your WinHttp example. mLipok 1 ♡♡♡ . eMyvnE Link to comment Share on other sites More sharing options...
