+Here's the webserver API, so you can work on the webserver.

+

+My personal goal is to make this interface simple, so that coding it

+will be like coding in some scripting language...

+

+

+

+char *get_param(char in_string[500], char swhat[500]);

+

+This function simply returns various data from the query string.

+	*Pass get_param NOTHING longer than 500 in length!

+

+	What do I pass where in_string is?

+		The query string.

+

+	What do I pass where swhat is?

+		One of two things...

+		Either 0 for the path of the 'page'

+		or you can pass it the param you wish to lookup. 

+

+

+

+

+

+

+char *get_query(char *inquery);

+

+This function simply returns a query string from the raw server request.

+This is used once in main, I doubt you'll need it.

+

+

+

+

+

+void web_send(int sockin, char *in_data);

+

+Super easy way of sending data to a webpage!

+Simply put in the socket name and then the data.

+

+	Ex:

+		web_send(socket, "I like cheese!\n");

+

+

+

+

+char *html_header(char* title);

+Easy way to print the eAthena header for the server.

+

+	Ex:

+		web_send(sockethere, html_header("About"));

+This readme is intended for the programmers of eAthena.

+

+This webserver's apis are in API.txt.

+

+To make this simple, generate.c should handle most of the work this sever does

+in terms of what people see.

+

+When a request is made the server shoots it off to generate.c.

+

+You are welcome to create more functions used by generate.c to generate pages

+though, so don't feel limited by that one file.
