I certainly know that is not true when hosting on Windows, on *nix I
believe it uses FastCGI. The user session data is only important for
when the user *has* a session (logged in or so?), otherwise you are
free to kill the session once served. The amount of data it holds is
only your own design, can be as little or large as necessary.

As you can see on the main site, it handles static content fine, plus
it can still pass through plain html (or theme it if you so wish).

True, but it can handle a very Qt style or design (which I personally
do not like, nor do I use it), or a very CSS centric style, or any

Oh not even, the main advantage of web design in C++ is its powerful
capabilities and ability to abstract things away. Since I started
using Wt I can get a site running faster then I ever could have with
PHP or Python (PHP of which I dealt with for near ten years, know it
quite well, and also how amazingly crappy it is). Everything is about
libraries, not language, as any good programmer knows, and Wt is a
truly excellent library.

What I meant by low level is that it has no higher level abstractions
as Wt has, it is nothing but pure MVC, where Wt is more like Qt (which
is MVS anyway, but like a GUI program, or you can use the lower-level
capabilities if you so wished). CppCMS does *not* do near what Wt
has, I tried it (I do prefer its license over Wt's), but it was not
anywhere near as useful, not as complete.

Wt is not a proof-of-concept, it is very well used out in the wild.

And it is a framework like Django and so forth, it just is capable of
even doing more then those, while still exposing any amount of power
that you would require (unlike those listed, where you tend to run
into limits very fast).

Good caching is useful, no matter what you use.

It is no where near as much content oriented in comparison. Wt
basically has two 'controllers' that you can use, one is stateful, the
other is stateless (as well as a third for just passing through static
files). One major difference is that you do not need to write
templates as in CppCMS (well, you could also write out raw html from
CppCMS), since Wt lets you design it like a Gui app, you can create
things *FAR* quicker (plus can still use CSS to lay them or, or use
sizers, the main Wt site uses CSS, which they recommend, they only
support desktop-like sizers for more Qt-oriented people, and the CSS
can by dynamically generated, static, etc...). Plus Wt has allowances
for all the main browsers so everything should look and act the same
everywhere (something which requires using a lot of if's in a
template). So on and so forth. I tried using CppCMS, but it just
does not do anywhere near as much to smooth the workflow in

Ditto, and a couple years of experience with Wt, and a decade with
PHP, and a few months with CppCMS.
