Custom compatibility

You can specify custom image requests that used the version 3.x and earlier solution versions' rewrite feature as you normally would. First, you must update the REWRITE_MATCH_PATTERN and REWRITE_SUBSTITUTION environment variables for your image handler function with the appropriate (JavaScript/ECMAScript-compatible) regular expressions and strings. For example:

https://<distName>.cloudfront.net/<customRequestHere>
