Server_Name regular expression

Server NGINX
1

I would like to syntax a regular expression which will match two server
names. The server names are example.com and www.example.com. In
particular,
a regular expression for www or nothing

I wrote the following regular expression (www.|)example.com Nginx
configuration file is compatible with Perl programming language. While
it
should work, it doesn’t seem to work. I cannot find the proper regular
expression. Does anyone have an idea how to synatx the regular
expression?

Thanks

How to use regular expressions in server_name directive is
documented here:

http://nginx.org/r/server_name

Note that regular expressions must be preceeded with “~” to
distinguish them from normal names.

Syntax of regular expressions per se is documented in the PCRE
library manual pages, see “man pcresyntax” for quick syntax
reference.

Irrespective of your use of this in an nginx config, you have made a
mistake constructing the regex. It’s such a simple one that I feel
relatively sure that you’re a newcomer to such things, hence I would
suggest you find a regex primer (book|website) and study it carefully.
