#3 Unlimited subdomain depth for AlwaysHC patch *.domain com

[Martin]

Upgrade of the AlwaysHC patch so it can use unlimited subdomain depth.

// NEW FUNC BEGIN

/*

Extract the domain name

*/

static int d_ex(char *search, char *domain)
{

char mdot[]=".";
char *array[142];
int loop;

array[0]=strtok(search,mdot);

if(array[0]==NULL)
{

return 1;

}

for(loop=1;loop<142;loop++)
{
array[loop]=strtok(NULL,mdot);
if(array[loop]==NULL)
break;
}

if(loop<2) {

return 1;

}

snprintf(domain,255,"%s.%s",array[loop-2],array[loop-1]);

return 0;

}

// NEW FUNC END
