Chapter 3. Managing Connections > Testing and Debugging Network Connections

3.5. Testing and Debugging Network Connections

Networked applications present some additional difficulties when testing or debugging programs, as more than one system is always involved. A connection attempt may fail for many reasons, including the following:

  • The target URI may be incorrect (watch for typos).

  • A username or password may be wrong.

  • The maximum number of licensed clients or maximum licensed bandwidth of the server may have been exceeded.

  • The network may be down or unreliable.

  • A connection that worked fine in a test environment may fail because of a firewall or proxy server.
