No.  The instructor at the MySql training class I attended, who is an
employee of MySql AB, specifically mentioned this example.  In the case
of a website, you are not distributing Mysql or any MySQL library or
components to your end users.   So no MySql Commercial license is
required.

#2 (allowing free use) from the licensing page would apply to any
normal website.

#3b (requiring a commercial license) would cover a non-gpl product
built using mysql drivers to connect to mysql, regardless of
whether or not you ship the mysql server with your app.

I suppose that if you used some non-GPL driver in your app, and
didn't ship the Mysql server or any libraries, then there is
nothing requiring a commercial license.  But I'm not sure if
there is such a driver out there.

I think the MySql licensing page is intentionally ambigous (at
least slightly), to get more people to buy the commercial
license.  In fact, there are several places on the page that
pretty much admit this.

Here's a link to the page, and two parts referenced above:

http://www.mysql.com/products/licensing.html

"2. Free use for those who never copy, modify or distribute

As long as you never distribute (internally or externally) the MySQL
Software in any way, you are free to use it for powering your
application, irrespective of whether your application is under GPL or
other OSI approved license or not.


3. Commercial use for everyone else

If your application is not licensed under GPL or compatible OSI license
approved by MySQL AB and you intend to distribute MySQL software (be
that internally or externally), you must first obtain a commercial
license to the MySQL software in question.

More specifically:

a) If you include the MySQL server in your non Open Source application,
you need a commercial licence for the MySQL server

b) If you include one of the MySQL drivers in your non Open Source
application (so that your application can run with MySQL), you need
a commercial licence for the driver(s) in question. The MySQL
drivers currently include an ODBC driver, a JDBC driver and the
C language library.

c) If you use MySQL Software within your organisation and you don't
  want to risk it falling under the GPL license, you are welcome to
purchase a commercial license.

d) Many users opt for the commercial licence simply because under
it MySQL AB takes responsibility for its products. Under the GPL
licence, there are no warranties or representations from the
developer (i.e. from MySQL AB)."
