<Fig 3.21: find_http_uri_type()>
Request-URI which is saved in URI [MAX_URI_SIZE] of st_http_request has URI Name before “?” symbol
and Query String after “?” sign. When Request-URI is transferred from Web Browser to Web Server, SP
(Space) text is transmitted in the form of ‘+’ and, other Reserved Texts are transmitted in the form of
“%HEXHEX.” Accordingly, Reserved Texts in Request-URI needs to be decoded to the previous value, from
‘+’ to SP and from %HEXHEX to related ASCII vales. For the details of Request-URI decoding, refer to
RFC1738. URI name of Request-URI is extracted with get_http_uri_name().Query String of Request-URI can
include one or more “variable=value” pair that has “&” as a separator. Through function
get_http_param_value(), it can extract the wanted variable value in Query String.
