Identify request in a flow of TTImageView - Reset picture cache

[CrazyKoala]

Hello.

In my project I;m using TTImageView to handle the retrieval of remote pictures through their URL.

But then I need to apply some different effect after the pictures are loaded, depending on the request that was executed.

I don't have the hand of the way the URL of the pictures are handled. (I'm retrieving pix from Facebook)

Is there a way I could use ETag that I could set up in the request before it gets sent  ?

Actually its an idea, any way for me to identify the request would be good enough.

My last problem is how do I avoid in certain cases the pictures being retrieved from the cache.

It seems that if the pic is loaded from cache, it won't go through any of the 3 delegate methods :/
