cURL equivalent for client / browser (not server)

Hey guys,

What would you say is the best alternative for going about loading HTTP/S pages exactly like cURL does, but using the user’s client / browser, as opposed to having the SERVER load HTTP/S pages?

I’m having trouble searching these things. Not exactly sure what to type to get good results.

Cross-Domain whatever…

Yeah but that requires that the two domains plan connections. cURL doesn’t require one domain to plan another to HTTP GET or POST information.

That is all you have. Use YQL in the other cases.

Ah so it would still be using / communicating with a server (Yahoo’s) in order to load pages, right? Thanks
