ASIHTTPRequest vs NSURLConnection

Question

Just wondering which is faster in terms of performance and usability? Or if there\'s anything better out there?

Answer 1

There's some performance information relating to an old version here:

http://allseeing-i.com/ASIHTTPRequest-1.5

It's pretty comparable. I'm not sure if there are any figures for more recent versions.

Note that the most recent ASIHTTPRequest has built in support for caching (which NSURLConnection doesn't) - if you enable that and it's applicable for your use it gets you a major speedup.

ASIHTTPRequest also does a lot of things for you for free; it can transparently handle HTTP Proxy authentication if you want it to, for example.

I pick ASIHTTPRequest over NSURLConnection all the time: for me the caching was the real major advantage, but everything else is certainly nice to have.

If you do decide to use ASIHTTPRequest, do use the latest git master, not the v1.7 release - the latter has some bugs that cause crashing when cancelling requests and a few other issues which are fixed in master.
