Creating BHO... http request

[bobetko]

I am trying to create Browser Helper Object and have couple of questions:
1) How can I make http Request?
2) How to Get Response?
3) How to get selected text (anything/word selected inside the browser)?

Any idea where to look for these info?

I am trying to do plugin which will enable user to select word anywhere in the browser and request language translation.
My request would be something like "

http://translate.com?word=success"

or, it would be even better if I could use POSTDATA.

Thanks.
