Understanding GWT-RPC Concept

Can anybody explain me about this thing?

X-GWT-Permutation:1F79347D29BC07C95FC8B3A262D5DC8E

i have tried decoding some of the strings using Base 64.

i am using the following base to decode strings like bwR2, bwSo, bwSn, bwTU...

Base = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789$_

i got this string from this type of Request Payload Header:

7|0|10|https://www.bosscapital.com/app/Basic/|B8CC86B6E3BFEAF758DE5845F8EBEA08|com.optionfair.client.common.services.TradingService|prepare2OpenPosition|J|D|java.lang.String/2004016611|I|1.11427|0|1|2|3|4|11|5|5|5|5|6|6|7|7|8|7|8|BHLE|bwRF|E|Po|1.11427|1.11427|9|0|49|10|1|

The X-GWT-Permutation header references a GWT permutation's strong name (the strong name is an MD5 of the generated JavaScript code out of the JavaToJavaScriptCompiler, before it gets passed to the "linker").
The value isn't actually checked, only the presence of the header (as a partial countermeasure against XSRF).

The GWT-RPC wire protocol is described in https://drive.google.com/open?id=1eG0YocsYYbNAtivkLtcaiEE5IOF5u4LUol8-LL0TIKU
