Hi: For those of you interested, these are the changes between -03 and -04 versions: - We have tried to save a few bytes in the dictionary by splitting certain headers (listed with priority 3 to 5) into two parts, a common substring, and the non-common substrings. This may allow to re-use the non-common substrings with other strings. We have added some descriptive text. The strings: "[CRLF]Accept-Contact: " 5 0000 0012 [22] 5 "[CRLF]Accept-Encoding: " 4 05FB 0013 [2] 20.2 "[CRLF]Accept-Language: " 4 05E8 0013 [2] 20.3 are now split into "[CRLF]Accept-" and the rest: "[CRLF]Accept-" 4 [22] 5, [2] 20.2, 20.3 "Contact: " 5 [22] 5 "Encoding: " 4 [2] 20.2 "Language: " 4 [2] 20.3 The strings: "[CRLF]Content-Disposition: " 4 03AE 0017 [2] 20.11 "[CRLF]Content-Encoding: " 4 0342 0014 [2] 20.12 "[CRLF]Content-Language: " 4 0465 0014 [2] 20.13 are not split into "[CRLF]Content-" and the rest: "[CRLF]Content-" 4 [2] 20.11, 20.12, 20.13 [2] 20.14, 20.15 "Disposition: " 4 [2] 20.11 "Encoding: " 4 [2] 20.12 "Language: " 4 [2] 20.13 The strings: "[CRLF]Min-Expires: " 4 06CE 000F [2] 20.23 "[CRLF]Min-SE: " 4 081F 000A [17] 5 are now split into "[CRLF]Min-" and the rest: "[CRLF]Min-" 4 [2] 20.23, [17] 5 "Expires: " 4 [2] 20.23 "SE: " 4 [17] 5 "[CRLF]Min-" 4 [2] 20.23, [17] 5 "Expires: " 4 [2] 20.23 "SE: " 4 [17] 5 The strings: "[CRLF]Proxy-Authenticate: " 4 0428 0016 [2] 20.27 "[CRLF]Proxy-Authorization: " 4 03B3 0017 [2] 20.28 "[CRLF]Proxy-Require: " 4 068A 0011 [2] 20.29 are now split into "[CRLF]Proxy-" and the rest of the strings: "[CRLF]Proxy-" 4 [2] 20.27, 20.28, 20.29 "Authenticate: " 4 [2] 20.27 "Authorization: " 4 [2] 20.28 "Require: " 4 [2] 20.29 - Appendix A.
