985	request_id variable, needs more documentation	gabor.farkas@…		"i'd like to use request_id, but there are several things i need to know about it before i can use it, and the documentation does not answer them:

1. is that raw bytes? or a hexadecimal number as a string?
2. how long (how many characters) is it?

i need to know these because for example, maybe i want to put it into a query-string, or a html-attribute... so i need to know if i have to base64-encode it manually, or that's not needed, and so on.

i think the documentation should tell us more about this variable. i understand i can look into the source code to see how it is generated, but that does not guarantee that it will not change with the next version."	enhancement	new	minor		documentation	1.11.x					does not make sense here.
