Documentation:
|
|
the servlet interface
|
|
an actual servlet for the AnomicHTTPD must provide a class that implements
|
|
this interface. The resulting class is then placed in a folder that contains
|
|
all servlets and is configured in the httpd.conf configuration file.
|
|
servlet classes in that directory are then automatically selected as CGI
|
|
extensions to the server.
|
|
The core functionality of file serving is also implemented as servlet.
