Lusca dstdomain ACL rewrite in Multi Thread

Make the functions below multithreaded, so, more than 1 CPU will be used when determining if a domain matches or not an ACL (source code from Lusca open source web proxy). Deliver production-tested code (I will set up the testing environment). static void aclParseDomainList(void *curlist) { // DUDU char *t = NULL; splayNode **Top = curlist; while ((t = strtokFile())) { Tolower(t); t = xstrdup(t); *Top = splay_insert(t, *Top, aclDomainCompare); if (splayLastResult == 0) safe_free(t); } } static int aclHostDomainCompare(const void *a, const void *b) { const char *h = a; const char *d = b; /* DUDU */ return matchDomainName(h, d); }
