Figure 3.33: Configuration of the Internal HTTP Proxy
Transparent Proxy Because HTTP requests from clients normally arrive on
port 80 so are ignored by the proxy, these requests can be redirected to
port 3128. For this, ‘Transparent Proxy’ must be activated.
Caching If HTTP requests are repeated, activate the option ‘Caching?’ to

in the corresponding entry field. It should not be less than 100 MB.
When you have finished all settings, confirm with ‘Next’.
