Origin Path

Identifies requests by the request URL’s relative path. This relative path comparison is performed on rewritten or redirected URLs.

Key information:

This relative path comparison is performed after Edgio rewrites or redirects the request. Rewrite or redirect a URL through the URL Rewrite and URL Redirect features, respectively. Use the Path match condition to match on the original relative path submitted by the client.
This relative path starts directly after the hostname.
For the purpose of satisfying this condition, query strings in the URL are ignored.
Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
- SPACE: %20
- &: %26
- %: %25
Matching against URLs that contain non-US-ASCII characters requires that you specify encoded Unicode characters (e.g., %E3%81%93).
- Encode all Unicode characters before setting the Value option. This match condition only accepts encoded Unicode characters.
  
  Example:
  
  You should include the following characters instead of こんにちは when defining this match condition’s value: %E3%81%93%E3%82%93%E3%81%AB%E3%81%A1%E3%81%AF
- The majority of user agents (e.g., web browsers) encode non-US-ASCII characters in the request’s query string before submitting the request to our CDN. By default, our CDN service does not decode those characters.
  
  Curl does not encode non-US-ASCII characters.

Origin Query String

Identifies requests by the query string of the requested URL. This query string comparison is performed on rewritten or redirected URLs.

Key information:

You may configure Edgio to rewrite or redirect a URL. This query string comparison is performed after Edgio rewrites or redirects the request. Use the Query String match condition to match on the query string submitted by the client.
The value associated with this match condition will be compared against the entire request’s query string.
For the purposes of this option, a query string starts with the first character after the question mark (?) delimiter for the query string. Therefore, the text specified in the Value option should not include a leading question mark (?).
Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
- SPACE: %20
- &: %26
- %: %25
Matching against URLs that contain non-US-ASCII characters requires that you specify encoded Unicode characters (e.g., %E3%81%93).

- The majority of user agents (e.g., web browsers) encode non-US-ASCII characters in the request’s query string before submitting the request to our CDN. By default, our CDN service does not decode those characters.
  
  Curl does not encode non-US-ASCII characters.

Path

Identifies requests by the relative path of the request URL submitted by the client.

Key information:

Although you may configure Edgio to rewrite or redirect a URL, this relative path comparision will always be performed against the request URL submitted by the client. Use the Origin Path match condition to match on a rewritten or redirected URL.
This relative path starts directly after the hostname.
For the purpose of satisfying this condition, query strings in the URL are ignored.
Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
- SPACE: %20
- &: %26
- %: %25

Certain requests may not return a valid postal code. A question mark (i.e., ?) will match requests for which a valid postal code could not be determined.

Progressive Download

Identifies requests by whether the device that issued the request supports the playback of audio/video while it is still being downloaded.

Query

Identifies requests by a query string parameter of the request URL submitted by the client.

Key information:

Although you may configure Edgio to rewrite or redirect a URL, this comparision will always be performed against the request URL submitted by the client. Use the Query Parameter match condition to match on a query string parameter for a rewritten or redirected URL.
Syntax: <NAME>=<VALUE>

Example: The following value is only satisfied when the request submitted by the client contains a query string parameter whose name is country and whose value is US: country=US
Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
- SPACE: %20
- &: %26

Query Parameter

Identifies requests by the value assigned to a query string parameter in the request URL. This comparison is performed on rewritten or redirected URLs.

Key information:

You may configure Edgio to rewrite or redirect a URL. This comparison is performed after Edgio rewrites or redirects the request. Use the Query match condition to match on a query string parameter submitted by the client.
Parameter name:
- Query parameter name comparisons are case-insensitive.
- Replace spaces in the parameter name with %20.
- Only query parameters whose name is an exact match to the specified value may satisfy this condition.
Parameter value:
- Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
  - SPACE: %20
  - &: %26
  - %: %25
- Specify multiples values through a regular expression (e.g., value 1|value 2).

Query String

Identifies requests by the query string of the requested URL. This query string comparison is performed on the request submitted by the client.

Key information:

You may configure Edgio to rewrite or redirect a URL. This comparison is performed before Edgio rewrites or redirects the request. Use the Origin Query String match condition to match on a query string of a rewritten or redirected URL.
The value associated with this match condition will be compared against the entire request’s query string.
For the purposes of this option, a query string starts with the first character after the question mark (?) delimiter for the query string. Therefore, the text specified in the Value option should not include a leading question mark (?).
Certain characters require URL encoding. Use the percentage symbol to URL encode the following characters:
- SPACE: %20

- The majority of user agents (e.g., web browsers) encode non-US-ASCII characters in the request’s query string before submitting the request to our CDN. By default, our CDN service does not decode those characters.
  
  Curl does not encode non-US-ASCII characters.

Random Integer

Identifies requests by performing a comparison against a random integer.

This condition is useful for applying an action to a random set of requests.

For example, if you set the maximum value to 2, then Edgio will randomly apply 0, 1, and 2 to each request. If you configure this condition to match when the value is greater than 1, then you can apply a set of actions to approximately a third of your requests.

Key information:

This condition generates a random integer between 0 and a user-defined number for each request. Edgio will compare the number assigned to the request to the value defined within this condition.
Define the maximum value for this random number generation through the Random Integer Range (from 0 to ?) option.
Define the value to which Edgio will perform a comparison through the Value option.

Referring Domain

Identifies requests by the referrer’s hostname. A referrer’s hostname is determined by the Referer header.

Key information:

Specify multiples values through a regular expression (e.g., value 1|value 2).

Region Code

Identifies requests by the code for the region (e.g., state or province) from which the request was issued.

Key information:

Identify the desired region by its region code. A region code, which consists of 1 to 3 alphanumeric characters, identifies a subdivision of a country by the region segment of the corresponding ISO 3166-2 code.

View ISO 3166-2 codes. (Wikipedia)

View ISO 3166-2 codes. (UNECE)

Example:

The ISO 3166-2 code for California is US-CA. Therefore, the region code for California is CA.
Certain regions have two levels of subdivisions. The specified value will be compared against the most specific region code.

Example:

A request that originates from the Devon (aka Devonshire) county of England, which is part of the United Kingdom (UK), has the following subdivisions: GB and DEV. Requests from this county will be matched against DEV.
Region codes are only unique within a country. In order to prevent false positives, we strongly recommend that you also add the Country match condition to your rule.

Example:

Requests from the following regions will report the same region code (i.e., SP):
- São Paulo, Brazil (BR-SP)
- La Spezia, Italy (IT-SP)
- Sandy Point, Bahamas (BS-SP)
Certain requests may not return a valid region code. A question mark (i.e., ?) will match requests for which a valid region code could not be determined.

Release Date

Identifies requests by the date on which the device that issued the request was added to the WURFL database.

Format: <YYYY>_<MM>

Example: 2022_december

Request Header

Identifies requests by request header value.

Key information:

Header name:
- Header name comparisons are case-insensitive.
- Replace spaces in the header name with %20.
- Only request headers whose name is an exact match to the specified value may satisfy this condition.
Header value:
- Specify multiples values through a regular expression (e.g., value 1|value 2).

Resolution Height

Identifies requests by the height, in pixels, of the device that issued the request.

Key information:

Specify height in pixels.
Specify height as a whole number.

Resolution Width

Identifies requests by the width, in pixels, of the device that issued the request.

Key information:

Specify width in pixels.
Specify width as a whole number.

Response Status Code

Identifies requests whose response matches a HTTP status code.

Key information:

You may use this match condition to apply features that affect the response provided to the client. For example, you may set response headers, a response body, or HTTP status code for all requests whose HTTP status code is 404 Not Found.

You may use this match condition to instruct the client to redirect requests by setting a Location response header to the desired URL and the response status code to a 3xx (redirection) status code (e.g., 301 and 302).

Edgio checks for this match condition upon receiving a response. At this point in the request flow, all features that correspond to the request or cache have already been applied.

Scheme

Identifies requests by their HTTP protocol: HTTP or HTTPS.
