What are the restrictions / limitations for adding custom, user-defined headers?
Created May 4, 2012
John Zukowski User-defined header names can consist of only printable ASCII characters, excluding the colon. They should start with an "X-", but there is no strict requirement that they do.
For example, the following would add a custom header to a message:
message.addHeader("X-FAQs", "http://www.jguru.com/faq");
