URL Path Extension

Purpose: Identifies requests by their filename extension.

The filename extension for a requested asset determines whether this condition is met. An option is provided to indicate whether this condition will be met when the filename extension "Matches" or "Does Not Match" at least one of the specified filename extensions.

Learn more about the core differences between the various URL path match options.

Key information:

• This match option looks for a URL that ends with a period (.) and the specified filename extension. Therefore, make sure that any filename extensions specified in the Value option do not contain a leading period.
  • Correct:
    htm
  • Incorrect:
    .htm
• The case-sensitivity of filename extension comparisons is determined by the Ignore Case option.
• Specify multiple filename extensions by delimiting each one with a single space. Sample syntax is provided below.
  htm html
• A filename extension value can take advantage of special characters.
• Each filename extension pattern can consist of one or more asterisks. Each asterisk will match a sequence of one or more characters.
• If a wildcard character (i.e., *) has not been specified, then only an exact match will satisfy this match option. For example, specifying "htm" will match for "htm" assets, but not "html" assets.

Sample Scenario

The following example demonstrates how this option works in specific situations:

Value	Description
asp aspx php html	This pattern will be satisfied when it finds any URLs that end with the following values: .asp .aspx .php .html
