First, your browser connects to the website's server and sends a URL of the document it wants to download web pages are documents, too and some details about the browser itself User-Agent etc.
The first line specifies which document the server should return. The other lines are called headers; they look like this:. If all is well, the server will respond by sending the requested document. The response starts off with a status message, followed by some headers with details about the document and finally, if all is well, the document's content.
This is what the SuperUser server's reply for my request looks like:. It means that the server has decided it can return a document, as requested, and promises that the contents that follow will be such a document.
If this is not the case the code will be something else, and it will provide some indication of the reason the server is not just returning a document as the response: for instance, if it cannot find the requested document, it is supposed to return Not Found , and if you are not allowed to access the content in question it is supposed to return Forbidden.
After this first status line, the response headers follow; they provide more information about the content being returned, such as its Content-type. Next is an empty line. It signals the fact that no more response headers will follow. Everything past that line is the content of the document it requested.
If I was requesting a document to download, it would probably be some gibberish characters, because most document formats are unreadable without prior processing. Back to headers. The most interesting one for us is the last one, Content-Length. It informs the browser how many bytes of data it should expect after the empty line, so basically it's the document size expressed in bytes.
This header isn't mandatory and may be omitted by the server. Sometimes the document size can't be predicted for example when the document is generated on the fly , sometimes lazy programmers don't include it quite common on driver download sites , sometimes websites are created by newbies who don't know of such a header.
