Are there strategies for caching both normal requests and Ajax?

[benbyf]

I have a site that uses both static requests and then continues with partial requests to urls using ajax and blocking out if(ajax) in my template. When making the static requests I use the built in caching in PW or Procache. However in order to recieve the partial request i have to use a cache burting GET parameter. Is there any way of making both of these requests cachable...? Only thing I could think of was having different urls with duplicate content.
