Systems and methods for capturing, logging, and diagnosing issues associated with web-based applications are disclosed. The systems and methods can include an interceptor application to intercept web-based (e.g., hypertext transfer protocol (HTTP)) requests and responses between web-based applications and third-party application servers. The systems and methods can also include an accumulator application to store request data and response data for a predetermined amount of time or until a predetermined number of requests and responses have been collected. The systems and methods can then send the accumulated data in a list or other data structure to a data logging server for storage in a database. The database can be used to diagnose issues arising on user equipment (UE), including issues caused by web-based applications.
