The basic page rule
If we have a page rule set to match:
example.com
It will match both http://example.com and https://example.com. You do not need to specify http:// or https:// to match in the page rule, unless you want to limit it to only trigger on that protocol. You do not need a wildcard (*) to match both http and https.
Wildcards
In page rules, the asterisk (*) can be used as a wildcard, for instance, if we have a page rule set to match:
example.com/a*z
It will match example.com/abcdz and example.com/axyz, the asterisk means it will match any subdirectory beginning with a and ending with z
Wildcard examples
example.com/* would match
https://example.com/anything
orhttp://example.com/anything
orhttp://example.com
but NOT a subdomain of example.com like subdomain.example.com .
Adding another wildcard before, such as:
*example.com/*
would match anything before the example.com as well, for example it would match https://example.com and also subdomain.example.com
Adding a dot after the first wildcard, such as:
*.example.com/*
would match anything before the example.com , but not example.com itself. It would match subdomain.example.com , but NOT example.com
Use with ‘Forwarding URL’
The page rule wildcards can be useful to match a section of your website or those of a certain file type, however it can also be useful when redirecting using the ‘Forwarding URL’ setting. It can then be used alongside the $ symbol in the URL to forward to.
For example, if you set:
example.com/*
Forwarding URL
https://www.example.com/$1
This would match any path on example.com and redirect it to the same path on www.example.com. E.g. example.com/abc would redirect to https://www.example.com/abc.
You can use $1, $2, $3 etc. to match any *.
You can read more in the tutorial, Deprecated - Using page rules to perform redirects.
Note that an ‘Orange Clouded’ DNS record is required for a page rule to run
For example:
If I wanted a page rule to match subdomain.example.com, then I would need to add a DNS record for subdomain and set it to
