add { url | host } (predefined URL category view)

Specifies a URL rule.

&<1-2> indicates that each command can configure a maximum of two strings at a time. When the URL contains over 255 characters, you need to enter two strings. The system automatically places the second string behind the first one to form a complete URL for matching. For example, if you configure add url www.example.com 123, the system stores it as www.example.com123 after processing.

• The value is a character string. If the URL does not contain any space or question mark (?), the length is 4 to 255 characters. If the URL contains spaces or question marks (?) (not at the end), the URL must be enclosed by double quotation marks ("") and the length is 6 to 255 characters. Pre-processing removes http:// from the entered character string.

• When you enter two strings, the URL obtained by combining the two strings contains a maximum of 480 characters.

• If the URL contains double quotation marks (""), you need to replace them with escape characters "%22". For example, if the URL is www.example.com/abc/def?"gh, you need to enter www.example.com/abc/def?%22gh.

• * indicates wildcard, which appears at the beginning, middle, or end of a URL and indicates suffix matching, keyword matching, and prefix matching, respectively. For example:
  • When the URL is configured as *abc, all URLs ending with abc are matched.
  • When the URL is configured as *a*bcd*, all URLs containing a and bcd in sequence are matched.
  • When the URL is configured as bcd*, all URLs starting with bcd are matched.
• If a URL does not contain any wildcard, the URL must contain at least four consecutive characters, such as abcd. If the URL contains wildcard, it must contain at least three consecutive characters except the wildcard, such as *abc, *abc*, abc**, and *a*bcd.

• If the entered URL ends with .*, there must be at least three common characters before .*. Take *.*.* as an example. It ends with .*. However, it does not contain three common characters before .*.

• If the total length of the entered URL is 4, only one * exists at the beginning, and the length of the remaining common characters is 3, the last character cannot be .. Take *ab. as an example. Its total length is 4 and begins with *, and the length of the remaining common characters is 3. However, its last character is ..

Indicates all URL rules.

Specifies a domain name rule.

&<1-2> indicates that each command can configure a maximum of two strings at a time. When the domain name contains over 255 characters, you need to enter two strings. The system automatically places the second string behind the first one to form a complete domain name for matching. For example, if you configure add host www.example.com 123, the system stores it as www.example.com123 after processing.

• The value is a character string and the length is 4 to 255 characters, without special character slash (/), back slash (\), number sign (#), double quotation mark ("), question mark (?), or space.

• When you enter two strings, the domain name obtained by combining the two strings contains a maximum of 480 characters.

• * indicates wildcard, which appears at the beginning, middle, or end of a domain name and indicates suffix matching, keyword matching, and prefix matching, respectively. For example:
  • When a domain name is configured as *abc, all domain names ending with abc are matched.
  • When a domain name is configured as *a*bcd*, all domain names containing a and bcd in sequence are matched.
  • When a domain name is configured as bcd*, all domain names starting with bcd are matched.
• If a domain name does not contain any wildcard, the domain name must contain at least four consecutive characters, such as abcd. If the domain name contains wildcard, it must contain at least three consecutive characters except the wildcard, such as *abc, *abc*, abc**, and *a*bcd.

• If the entered domain name ends with .*, there must be at least three common characters before .*. Take *.*.* as an example. It ends with .*. However, it does not contain three common characters before .*.

• If the total length of the entered domain name is 4, only one * exists at the beginning, and the length of the remaining common characters is 3, the last character cannot be .. Take *ab. as an example. Its total length is 4 and begins with *, and the length of the remaining common characters is 3. However, its last character is ..
