Re: [Dev-C++] Anybody???

[Per W. <pw...@ia...>]

Have you read up on the HTTP protocol?

If your server claim that it users a modern version of the HTTP protocol,
then most web browsers will issue several requests on the same connect. If
you claim that the server only supports standard 1.0, then the browsers
will have to make new connects for each request.

There are no magic involved with winsock - your problems doesn't have
anything to do with winsock, but with understanding the HTTP protocol, and
what a web server is expected to do.

A client should not know anything about c:\Dev-Cpp\images - your web
server should have a defined root directory, and should figure out all
paths either based on that root directory or on individual path
translations.

You can also affect what requests the web browser makes by switching
between absolute, relative and fully qualified image names.

Some possible links you might have in the served document:
<a href=3D"http://<ip>/images/image1.gif">
<a href=3D"/images/image1.gif">
<a href=3D"images/image1.gif">

If you specify a relative path, then the client (the web browser) must
perform it's request relative to the main document. With an absolute path,
it is enough to use the same connect - or a new connect to the same
server. With a fully qualified URL, the web browser may connect to any web
server to retrieve an image.
