A method, system, apparatus, and computer program product are presented for recordation and playback of transactions within a web browser or similar client application. A transaction recordation and playback utility captures dynamic information upon recordation and/or playback of a web-browser-based transaction. The dynamic information is derived from the DOM-related (Document Object Model) information that is maintained within the web browser application. Using information from a previously recorded transaction, the transaction recordation and playback utility searches the current DOM-related information for current values of dynamic parameters, thereby allowing generation of a complete and appropriate HTTP request on every subsequent playback of a recorded transaction.
