You may wish to exclude URLs from inspection by CrowdHandler when using our DNS implementation. These might be URLs that are unnecessary to check -- such as common assets (we exclude these by default). There are other URLs you may wish to exclude when you do not want calls to URLs to be cached under any circumstances. For example:

1. External API Feed calls

2. Payment provider call-backs

To exclude such URLs go to

Domains > DNS > Settings

and locate the URL Exclusion List:


Each exclusion rule goes on a separate line.

CrowdHandler users Amazon's CloudFront service. It uses it's own wildcard pattern matching format, which is detailed here:

You can use the following wildcard characters in your path pattern:

  • *matches 0 or more characters.

  • ?matches exactly 1 character.

The following examples show how the wildcard characters work:

Path patternFiles that match the path pattern

*.jpg

All .jpg files

images/*.jpg

All .jpg files in the imagesdirectory and in subdirectories under the imagesdirectory

a*.jpg

  • All .jpg files for which the file name begins with a, for example, apple.jpgandappalachian_trail_2012_05_21.jpg

  • All .jpg files for which the file path begins with a, for example, abra/cadabra/magic.jpg.

a??.jpg

All .jpg files for which the file name begins with aand is followed by exactly two other characters, for example, ant.jpgand abe.jpg

*.doc*

All files for which the file name extension begins with .doc, for example, .doc, .docx, and .docmfiles. You can't use the path pattern *.doc?in this case, because that path pattern wouldn't apply to requests for .docfiles; the ?wildcard character replaces exactly one character.

The maximum length of a path pattern is 255 characters. The value can contain any of the following characters:

  • A-Z, a-z

    Path patterns are case-sensitive, so the path pattern *.jpgdoesn't apply to the file LOGO.JPG.

  • 0-9

  • _ - . * $ / ~ " ' @ : +

  • &, passed and returned as &
