Order of messages in answlog.log

[ZeronSix]

I want to be able to automatically parse answlog.log for server requests and responses. To do so, I have to match the requests with the corresponding responses. As far as I understand, there is no guarantee that the response to a request will directly follow that particular request in the log. For example, it can be:

Request A
Response A
Request B
Response B

or

Request A
Request B
Response B
Response A

So, is it possibly to properly order the log messages?
