The regset() function allows you to parse a string (e.g. a URL or header value) according to a regular expression and to set several variables at once to selected substrings of the input string, optionally converting between different types. For example, the fragment below sets ttl and grace parameters of the object according to the Surrogate-Control header: variable.regset("ttl:d=\1s,grace:d=\2s", "^(?:.*,)?max-age=([0-9]+)(?:+([0-9]+))", beresp.http.Surrogate-Control); set beresp.ttl = variable.get_duration("ttl"); set beresp.grace = variable.get_duration("grace"); @@ -154,25 +154,25 @@ VOID global_unset(STRING name) VOID global_clear() Unset all global variables * vmod_variable vs. vmod_var This module is backward-compatibile with vmod_var.
