Headercut Channel Options

Cutting header to fit
The  channel option cuts the current message header down to no more than the specified number of bytes using a heuristic algorithm that removes or truncates header fields based on their relative importance. Unlike, which should be used to deal with issues of the mere presence, or the number, or the size, of specific header fields,   is intended for use to meet constraints on overall header size.

The  option requires a single nonnegative integer argument. A value of 0, the default, disables header cutting.
