what part of the F5 BIG-IP does not allow them?

 

in general you see different kind of products not really liking underscores in HTTP header although the RFC doesn't disallow them. perhaps it would be better to stay away from them.

 

as for iRule just browse here, there are many good articles on them. but first explain your need a bit better.
