NAME
vmod_accept - Accept VMODSYNOPSIS
import accept [as name] [from "path"]
new xrule = accept.rule(STRING string)
VOID xrule.add(STRING string)
VOID xrule.remove(STRING string)
STRING xrule.filter(STRING string)
DESCRIPTION
accept allows you to sanitize the Accept* headers (mainly Accept, Accept-Charset and Accept-Encoding) by specify one fallback string, and then adding valid values:
sub vcl_init {
new rule = accept.rule("text/plain");
rule.add("text/html");
rule.add("application/json");
}
You can then use the rule object to filter the headers. The following line will set the accept header to "text/html" or "application/json" if any of them is found in the original header, and will set it to "text/plain" if neither is found:
sub vcl_recv {
set req.http.Accept = rule.filter(req.http.Accept);
}
accept will ignore any parameter found and will just return the first choice found. More info here: https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
