[DUG] HTTP Server

[Jeremy Coulter]

Your right Phil.....its not the reply I am after :-)
 
what I want to do is simply use it for inter app. communication, EXCEPT,
that one app. might be on another machine. If I was sure they would be on
the same machine, then I would have used COM as it would certainly work for
what I want to do.
Its nothing more than passing an ACTION and then some other parameters, then
geting a simple response back. Nothing too scary, BUT I didnt want to have
to go down the whole TCPIP build your own nasty system, just something
simple, that is just a command and a reply, which HTTP works fine for and I
dont have to worry about connections etc. etc.
As for the ports, the ports are not an issue, can be changed from 80 if I
want, and prob. will.
The other idea behind using HTTP is that when other developers what to tap
into our app. then its a pretty easy way to interface to, to pass commands
to it etc.
 
further to this, I just found out why I was having a problem with Indys HTTP
Server, I was not clearing a collection and was getting multiple parameters
being sent to the http server (using HTTP POST)....DOH....now it works fine
:-)

Jeremy,

I know you probably aren't after this kind of reply, but I would reconsider
your approach. If you are building this functionality into an application
that has other desktop uses (eg, a word processor etc) then consider using a
TCP interface instead since it won't tie up port 80 which may be used for
browsing the web. If you are building a server based app that will just sit
there and respond to requests, then consider building an ISAPI DLL (very
straightforward). An ISAPI DLL will run under under the IIS on Win2000 so
you don't need to worry about getting a server version.

Phil.

Hi All. I want to add some functionality to my App. so that it uses an HTTP
server to receive commands and pass back a success or fail.
I have looked at the INDY and ICS HTTP Server controls, but they seem
slightly more complex than I need.
All I want to do is go, I have a POST, therefor fire this function and based
on the boolean result, send back a yes or a no.
I have looked at the Synapse HTTPServer demo, and it is just what I think I
need, but firstly threads do my head in, I would need to call a function on
the form that is the parent for the HTTP Server and pass back a boolean
value so it knew what to reply, but like i say, threads do my head in.
 
Has anyone else got a res. good HTTP server control/code OR managed to do
what I want to do with the Synapse controls?
