Description
Problem:
I want to be able to make decisions in DelegatingHandler based on the client
interface method being executed.
Specifically I want to apply retry logic to some requests. I would like to be able
to have one DelegatingHandler type for that and be able to somehow mark
interface methods where retry should be allowed. Deciding only based on request
method is not enough.
Describe the solution you'd like
One possible solution is to add another property to HttpRequestMessage.Properties/Options
that would contain MethodInfo of the method. Then I could define custom attribute that can
mark methods where retry is enabled and my DelegatingHandler could look for that attribute.
Another solution could be to add a new attribute like ConstantProperty that could be used
on method. It would work like existing PropertyAttribute with the difference that the value
of the property would be specified in constructor and would be constant. Again, I could look
for that property in the DelegatingHandler
Describe alternatives you've considered
I don't really see how could this be done today in a clean way. The only way to pass additional
information to DelegatingHandler is through PropertyAttribute but that requires adding
method parameter which is not right. Caller shouldn't have to pass another value to each
method to manage how the client works internally.
