http_status_matches
Available inall subroutines.
Determines whether the HTTP status matches or does not match any of the
statuses in the supplied fmt string.
Returns true when the status matches any of the strings and returns false
otherwise. If fmt is prefixed with !, returns true when the status
does not match any of the strings and returns false if it does. Statuses in
the string are separated by commas.
This function is not prefixed with the std. namespace.
Example
The following snippet in vcl_fetch marks backend responses with status codes
other than 200, 301, or 302 as not cacheable.
if (http_status_matches(beresp.status, "!200,301,302")) { set beresp.cacheable = false;}Try it out
http_status_matches is used in the following code examples. Examples apply VCL to real-world use cases and can be deployed as they are, or adapted for your own service. See the full list of code examples for more inspiration.
