set missing header
can i configure a request header transform rule to set a header if it doesnt exist?
Ie.g if the http request referer header does not exist, set it to a default value
EExpression:
EAnd then just set the header as the action
Ecan be seen in action on https://headers.erisa.uk which is a worker that returns the request headers in the body and will default
myheader to defaultvalueE
EIn my expression you could swap out
!not and == for eq and it would work the sameEMy brain tries to treat it like code so I end up using the C-like notations
