Configuring the NetScaler for web server logging

To configure the NetScaler for web server logging you are required to only enable the Web Server Logging feature. Optionally, you can perform the following configurations:

• Modify the size of the buffer (default size is 16 MB) that stores the logged information before it is sent to the NetScaler Web Logging (NSWL) client.
• Specify the custom HTTP headers that you want to export to the NSWL client. You can configure a maximum of two HTTP request and two HTTP response header names.
