Hi,

I want to ask how can one write a software application which can automate browser processes such as loging into a site, posting some content and loging out.

There are a number of softwares out there in market which do so, but i am familiar with them from a long time ago, they need windows explorer to work.

I have searched a lot but could not find, in which language they are coded. Can some one put a guide or an article which will get me started on the process?

Thanks
