URL encoding is handled here in a simplistic way. You may 
want to expand on this by encoding other characters (such as 
&lt;, &gt; &copy; and others).<br>
<br>
<code>
char *urlEncode(char *s, char *param) {
 	char *c;
	     
	strcpy(s, param);
	c = s;
	while (*c != '\0') {
		if (*c == ' ') *c = '+';
		c++;
	}
	return s;
}
</code>
<br>
Now, we need to form all of the request headers from beginning 
to end:<br>
<br>
<code>
char *formRequest() {
	char *post;
	int len;
	char cLen[32];
	char *protocol = "POST "; 
	char *request;
	int i;

	post = formContent();
	len = strlen(post);
	sprintf(cLen, "%d", len);
	len = 0;
	len += strlen(protocol);
	len += strlen(action) + 1;
	len += strlen(headerStuff);
	len += strlen(cLen) + 6;
	len += strlen(post);
															   
	if ((request = (char *)malloc(len)) == NULL) 
		die("Out of memory!");
	strcpy(request, protocol);
	strcat(request, action);
	strcat(request, " ");
	strcat(request, headerStuff);
	strcat(request, cLen);
	strcat(request, "\r\n\r\n");
	strcat(request, post);
	strcat(request, "\r\n");
																								   
	free(post);
	return request;
} 
</code>
<br>
It should be apparent why we formed the name/value pair request string in 
a separate function -- we need to measure it by itself and tack the result 
onto the end of the <i>Content-length</i> header. This is to notify the 
server of how much body is about to come so the connection will stay open.<br>
<br>
Remember, too, that <i>char *post</i> was created by a <i>malloc</i> in the 
function <i>formContent(),</i> so we need to free it. Likewise, the 
caller will have to free the return from this function as well.<br>
