Plain old vanilla gzip compression works great. If transmitting XML over HTTP (a very common use case), the HTTP spec explicitly permits compression of content. You can include "Content-Encoding: gzip" as an HTTP header, and achieve a high-level of compression (80%-90% in my experience) while still fully conforming to the HTTP spec. The only downside is that many XML messaging toolkits may not properly support this. > -----Original Message----- > From: Roger L.
