In the VuGen Recording Log, you can find all the dialogue between the browser and the server, including communication content, date, time, the browser requests a response from the server, etc.. Recording Log script and the biggest difference is that the script only records the client side to say on the server side, while the Recording Log is a complete record of the two dialogue.

So the record in the script to the server said, complete with the original recording said, write die (hard-coded). This approach in the face of some clever server, or failure. Then you need to through the association (correlation) approach to allow VuGen to successfully fool the server again. What is the relevance (correlation)? The so-called Association (correlation) is to write script some dead (hard-coded) data is retrieved from the server into a send, dynamic, not every time the same data. A common example just mentioned some of the more clever servers, these servers in each browser first with it when the data in the data will be entrained in a unique identification code, then use this identifier to identify with it to data is not the same browser. The general said the identification code for Session ID. For each new transaction, the server will produce a new Session ID to the browser. This is why the reason t
