appfabric read through - passing parameters

Question

 i have implemented the read through mechanisum but i require  parameters to be passed though to the read function so that i can pass these to a webservice to  generate the new cacheitem

(apart from  using the key as a parameter source)

is this possible?

Thanks Paul

Answer 1

basic serialization of the class to string  throws an exception from  appfabric  when passing as  the key

the answer seems to be to JSON serialize the object and that passes as the key ok
