Length property

Read-only.
This property are set after FetchData call. It contains the number of bytes received from server (without response headers).

Notes

The length of document is also contained in the "Content-length" response header field, but server is not obliged to send it. You can get the response header field through the Fields object. The example below shows the both values:

http.FetchData url
docsize=http.Length
declared_docsize = http("Content-length")
