Configuring the Symantec Web Gateway HTTP proxy and HTTPS proxy
Symantec Web Gateway has a proxy that you can enable for HTTP and HTTPS network traffic. The HTTP/HTTPS proxy supports HTTP version 1.0 and version 1.1.
For the HTTP cache, Symantec Web Gateway honors the cache-related code in downloaded HTTP files.
To configure the Symantec Web Gateway HTTP proxy and the HTTPS proxy
In the Web GUI, click Administration > Configuration > Proxy.
Under HTTP Settings, check Enable HTTP/S Proxy.
For HTTP/S Proxy Port(s), type one or more ports.
The proxy listens for HTTP traffic from user Web browsers at the ports that you specify. You can type individual ports or a range of ports. Separate a range of ports with a dash. Use commas to separate ports. You can configure a maximum of 16 ports.
The default ports are 8080 through 8083.
Type a number for the Maximum Cache Object Size.
Files over the number of megabytes that you specify are not retained in the cache on Symantec Web Gateway. The maximum size is 256 KB.
The default is 256 KB.
Type a number for the Keep Alive Timeout.
The Keep Alive Timeout is how long the proxy keeps a network connection open after the last transmission. The maximum is 1800 seconds (30 minutes).
The default is 120 seconds.
Check or uncheck Byte Range Support.
The byte range support determines whether partial requests for data are served from the cache or fetched from the Internet.
Byte Range Support checked
HTTP and HTTPS requests under 14 KB are served from the cache. If the requested files are not already cached, the data is fetched, cached, and passed along. Requests that are over 14 KB in size bypass the cache and are served from the Internet.
Byte Range Support unchecked
Partial responses are fetched and passed along but not cached.
The default is checked. The 14 KB byte range cannot be changed.
If you want, click Add a Cache Exception to add a domain that you do not want cached.
Data is not cached for the domains that are listed under Cache Exception Domain. You may want to exclude the Web sites that mainly stream content. In some cases, you may want to exclude internal Web servers.
The maximum number of cache domain exceptions is 30.
