ISAPI question?

Been developing a web app which runs in PHP but gets it's data from a dll module e.g.

Http://<server>/scripts/data.dll?command=GetNews

However all this is fine and dandy but I am really unsure on how to pass the data back to the server.

The data will hopefully be xml but would it be easier to pass it back through the url, or as a data/form post or what???

The best way would be to either use sockets yourself or curl, do a search on both here and php.net and you sure will come up with something.

P.S. what is it doing in windows forum?

Didn't know where to put it, because the ISAPI filter was writen in DevStudio and IIS and all that I went for Windows.

Where would you recommend I post this topic? For maxium results?

I am not familiar with all aspects of dlls so probably I am missing a point here. Would you go over problems you face while working with dlls? I haven't had any first hand experience with them.

As for the topic, I would use something like 'exchanging data dll-php' or something of that matter.

Maybe I'm not too clear about the question either, but are you asking how to make an ISAPI dll return data back to the webserver? If so, I can probably give you a hand with that.

sorry guys, i'll try again

I got a dll that sends data (XML) to the client/browser, so in my php file where I process/parse the XML I can this:

$xml_data_file = "http://SERVER/data.dll?command=<command>

so when I pass a command like, GetNews, or GetUsers it's sends that data back to the php file to parse.

When I change the data, client side, I want to pass the data back to the server, preferrably in XML too, but i'm unsure as to how to pass the data back, I dont want to have to pass it in the URL e.g.

http://SERVER/data.dll?command=Save...oomuch=data&etc etc etc

So I was wanting to know the best way to give this dll some data back.

Hope that was better.
