The modules referred to as EWSAPI  modules are the modules
that implement part of the webserver as mod_get, mod_log, mod_esi etc
and it is possible to replace mod_* modules with your own variant or
extend with new mod_* modules.  Which  mod_* modules that are used
when processing a request is determined by the modules  property
equvialent to the Apche like directive"Modules".

A mod_* module should implement the callbacks documented in
the httpd man page.

You can also read about this in Inets Users Guide in the section 
"Dynamic Web Pages"

http://www.erlang.org/doc/apps/inets/part_frame.html

and "ErlScriptAlias"  and other properties of the web server  are 
documented in the httpd manualpage.
(Note: The above format is if you use Apache-style configuration files 
for the HTTP server, from
inets-5.0,  R12B it is also possible to use erlang-style property-lists 
both directly and stored in a file
to start a HTTP server. Also note that there are more default values 
since R12B)
