Yes, I could provide a list_remove implementation - problem is, I think that the request->headers_in convenience fields point to elements of the .headers list, yes? Given that list elts is an array, re-organizing that array would invalidate the pointers of headers_in. Right ow, I think that renaming the header in question and setting the headers_in field to null is probably the only option. What do you think?
