Hi Dears!
I am thinking about working with remote data and receive or send data actually in external web sites. we have a large amount of examples in World Wide Web are working. For example: free online web tools like web stats OR Google's Ad Scene .... .
you know in such web services some code will generate for publishers and the publisher put generated code in her BODY of web page document( HTML file) and the system after that will work.
we can have count of visits for home pages, count of clicks on advertisements and so on.
now this is my question: How such systems Work? and how can I investigate and search about them to find out how to program them? can you suggest me some keywords? Which Titles should I looking for?
if my Q is not Clear I will Explain it more...
