 |
|
Can I use a TCPClient to access and read an HTML page hosted
in a webserver ? I don't would to use the TIdHTTP object because
I've already open a TCPClient to a site in which port 80 get me
HTML contents and port 1080 get me TCP contents...
Thank you very much..

I don't see your problem with HTTP. The 'port 80' is the listening port for
the HTTP servers on the remote sites. You can have loads of TidHTTP clients
running to different sites/servers. In fact, you can have several TidHTTP's
working against the same server, if you want, (unless the server itself has
some restriction on multiple connections from the same client IP).
Same with 'plain' TCP clients - open as many as you want, (within reason!).
Rgds,
Martin

Technically yes, though you would have to implement the HTTP protocol
manually. I do not advise doing that as the protocol can be quite complex
to implement manually.

Why not? You should. It already does all of the hard work for you.

So? Why can't you switch over to an HTTP client component for port 80?
There is nothing stopping you from using multiple components for different
purposes.

Hmm. I suggest some further reading about "source ports" and "destination
ports".
