Does Muse Proxy work with a Cloudflare secured site?

To make sure Muse Proxy rewrites a website protected by Cloudflare the most reliable way is for the publisher to list the outbound IP address at Cloudflare. This is a must especially if the Cloduflare challenge is set to Interactive Challenge (the captcha-like one).

For publishers not intending to support rewriting proxies, if the publisher site is set up with a non-interactive JS challenge, then the Muse Proxy source profile can be configured using a base64 filter:

<FILTER>
<PATTERNS>Use corresponding URL patterns here</PATTERNS>
<FIND><![CDATA["(aHR0cHM6Ly[^"]+)",]]></FIND>
<REPLACE base64="true" rewrite="1"><![CDATA["$1",]]></REPLACE>
</FILTER>

Also some Cloudflare cases may require the following profile settings
<KEEP_HEADER_ORDER>true</KEEP_HEADER_ORDER>
<SSL_CLIENT_ENABLED_PROTOCOLS>TLSv1.3</SSL_CLIENT_ENABLED_PROTOCOLS>
<SSL_CLIENT_PROTOCOL>TLSv1.3</SSL_CLIENT_PROTOCOL>
