If your expression includes any of the ^
, [
, .
, $
, {
, *
, (
, \
, +
, )
, |
, ?
, <
, >
characters and you want them to processed as plain text, you need to "escape" the character by preceding it with a backslash. For example, if your expression was application/epub+zip
this would need to be written as application/epub\+zip
otherwise the +
character would have a special meaning and no matches would be made. Similarly, if the expression was example.com
, this should be written as example\.com
, as .
means "any character" which could lead to unexpected matches.
This table outlines the different compare options available. The example match is based on the following sample address

Option | Description |
---|---|
Enable this rule | Specifies if the rule is enabled or not. Disabled rules will be ignored |

Include | Specifies that the URL should be included. This allows you to have a wider rule to exclude content, and then a narrower rule to include specific content. |
Crawl Content | Specifies that although the URL is excluded, its contents should still be scanned (applies to HTML documents only). This means that although a permanent copy of the URL is not downloaded, a temporary copy is still made in order to scan for additional URLs to crawl. |

Stop processing more rules | By default all rules are processed sequentially. You can use this flag to control this process; if set and the rule is matched, no further rules will be processed |
Download Priority | Allows the download priority for URLs matching the rule to be changed. High priority will mean the URL will be downloaded immediately, while Low means the URL will be downloaded when all other URLs have been processed1. |
1 The Download Priority options is only supported for rules that match against a URL, it is ignored for rules matching against content types.
