This chapter contains information about how to resolve problems when using MashupHub.
Enabling Debug Logging: imc3
When MashupHub logging properties are set to the DEBUG option, diagnostic information is logged for each request to MashupHub. Information such as request attributes, headers and cookies, session information and properties, memory usage state, and available WSSubject user principals is logged, and can be used to troubleshoot MashupHub problems.
