Web server processes can host multiple web applications that process multiple requests from multiple clients. Recorded diagnostic information may not provide a useful separation of server execution data (e.g., functionality executed to process a request) based on a client's use of the web server process. An effective method for separating server execution data by client information is provided herein. Dye is injected into a request from a client, the dye comprises information regarding the client application making the request and a transaction (e.g., client defined set of requests) that the request is comprised within. The dye injected request is sent to a web server process (e.g., on a web server) that extracts the dye and executes the request. During execution of the request, executed functionality is associated and stored with the extracted dye. The recorded server execution data may be organized based upon the request, client, application, and/or transaction.
