Wapp Limitations ================ The current Wapp implementation has the following limitations: 1. The actual page generation step is single threaded. Multiple connections can be incoming and multiple replies can be in-flight at the same time. But the generation of each reply happens all at once. <p> This limitation can be worked around by deploying the Wapp application using CGI, such that each HTTP request is handled by a separate process.
