Sets the type of regular expressions to use in request matching
statements. Allowed values for type are: posix and
pcre (or perl), case-insensitive. The latter requires
compilation time support.
The selected regular expression type remains in effect for all request
matching directives that follow this statement, until next
RegexType statement or end of the configuration file, whichever
occurs first.
Regular expression type can be set individually for a directive, using
the -pcre or -posix option (see Table 9.2).
See Regular Expressions, for a detailed discussion.
Ignore case when doing regex matching (default: ‘false’). This
directive sets the default for the following service matching
directives: URL, Path, QueryParam, Query,
StringMatch, as well as for the DeleteHeader
modification directive. Its value can be overridden for specific services.
This statement is deprecated and will be removed in future versions. Please, use the -icase option to the matching directive instead (see Table 9.2).
