An additional safety feature is stopping of asynchronous handlers when the
associated client or server object has been destroyed. An atomic instruction
based class, ScopeRunner, was implemented to achieve this since reader-writer
locks proved more resource intensive for this specific task.
locks proved more resource intensive for this specific task. In detail, a
ScopeRunner object has an internal atomic counter that is increased when an
asynchronous handler is run. At the end of the handler, the counter is
decreased. When the destructor of a client or server object is called, the
ScopeRunner object delays the destructor until its internal counter is 0, then
sets the counter to a negative value. Finally, when the internal counter is
negative, the handlers are returned from instead of potentially calling methods
or using member variables of a destroyed client or server object.
Compared to using a low-level network library, specialized for a specific task,
a slight performance overhead is expected when using the more generalized
Simple-Web-Server library. The various utility and safety features, and code
abstractions contribute to this overhead, but a good balance between safety,
usability and speed is continuously sought during development of this library.
Regular expressions can for instance be used to define which functions to be
called for specific request paths. This can be convenient for the library user,
but a more specific algorithm can be more efficient than using regular
expressions.

for the Simple-Web-Server project was to create a HTTP/1.1 library that was
relatively easy to modify and extend to suit a specific need, which could also
be positive with regards to source code contributions to the project.
There are several alternatives to Simple-Web-Server. Most notably Boost.Beast
