Filtering HTTP for browser-generated traffic

HTTP has a wide variety of encapsulated content. HTTP header values often define the type of content in the stream. The header values are name value pairs. For example the program that launched an HTTP request is often described after the header name User-agent.
This example filters HTTP headers based on the User-agent to capture data from browsers. These browsers contain User-agent values of Mozilla or Opera.
  1. To filter HTTP headers based on the User-agent
  2. Select
    System > Settings > Protocols
    from the navigation bar.
  3. Select the HTTP protocol.
  4. In the
    Filtering (may override at server level)
    section of the page, enter the following in the
    Content
    field:
    I,user-agent:,mozilla,opera
  5. Click
    Save
    , and then restart the servers.
If you use a custom configuration, you must make the same change in every server’s HTTP configuration.
