About URIs and the URI List

Each URI List Object must have at least one URI in its URI List. You can manually add entries to the URI List by typing or pasting them in or importing a list of URIs from a text (.txt) file. The file can be a manually created one or a file that was previously exported from the appliance. Each URI in the file is on its own line.

You can export the URI List contents into a text file that you can import later.

The URIs and URI List have the following requirements:

• Each URI can be up to 255 characters.
• The maximum combined length of all URIs in one URI List is 131,072 (1024*128) characters, including one character for each new line (carriage return) between the URIs.
• By definition, a URI is a string containing host and path. Port and other content are currently not supported, but you can use Keywords to match these.
• The host portion of a URI can be an IPv4 or IPv6 address string.

• Each URI can contain up to 16 tokens. A token in a URI is a string composed of the characters:

  • 0 through 9
  • a through z
  • A through Z
  • $ - _ + ! ' ( ) , .
  • Each token can be up to 64 characters, including one character for each separator (. or /) surrounding the token.
  • An asterisk (*) can be used as a wildcard representing a sequence of one or more valid tokens, not one or more characters.

  Examples of valid URIs	Examples of invalid URIs
  news.example.com news.example.com/path news.example.com/path/abc.txt news.*.com/*.txt 10.10.10.10 10.10.10.10/path [2001:2002::2003]/path [2001:2002::2003:*:2004]/path/*.txt	Using the wildcard character (*) incorrectly can result in invalid URIs such as: example*.com exa*ple.com example.*.*.com The wildcard character represents a sequence of one or more tokens, not one or more characters.
