  First of all, thanks for those clarifications...

  I believe that what you're saying act as a plus to the 'Header-Request' 
proposal. What you're showing here is in fact a (another ?) clue that 
something like this is actually needed but doesn't exist (yet ?), which leads 
to proprietary, non-standard "solutions". Do you actually believe that having 
a standard way to do these things will not be a benefit? Why not propose a 
standard to fit those needs?

  As for the req.requested_headers (I suppose you're referring to mod_python), 
I find it usefull... :-) (speaking for myself) 

  Finally, you should consider that newer "clients" will not need to introduce 
their own proprietary methods (like the javascript and plugin solutions you 
proposed), which of course saves us from interoperability and compatibility 
issues.
