[reSIProcate] Accessing a header by name determined at runtime

[Matthew Hodgson]

Hi all,

I'm trying to access a header's value by name - but with a name 
determined at runtime (e.g. Data headerName) rather than by a header 
token (e.g. h_To).  I was assuming that ExtensionHeader could be used 
for this by passing in the name of the header when constructing the 
ExtensionHeader - but I just realised that it asserts that you're not 
trying to define a header which already exists, and so can't be used for 
dynamically accessing wellknown header types.

I appreciate this is a bit perverse & contrary to the way resip takes 
pains to nicely type & parse known header types - but can anyone suggest 
how I might do this?

thanks in advance,

Matthew.
