They do not. A Lynx reload does this on the Squid cache:

REQ_HIERARCHICAL is SET which is not the case with Netscape, because of
the IMS.
The routine which determines if the request can use hierarchy does not
use "Pragma: No-Cache". A bug? IMHO, no. A reload should be transmitted
and update the whole hierarchy.
static int icpHierarchical(icpState)
icpStateData *icpState;
{
char *request = icpState->url;
request_t *req = icpState->request;
method_t method = req->method;
wordlist *p = NULL;
if (BIT_TEST(icpState->flags, REQ_IMS))
return 0;
if (BIT_TEST(icpState->flags, REQ_AUTH))
return 0;
if (method != METHOD_GET)
return 0;
/* scan hierarchy_stoplist */
for (p = getHierarchyStoplist(); p; p = p->next)
if (strstr(request, p->key))
return 0;
if (BIT_TEST(icpState->flags, REQ_LOOPDETECT))
return 0;
if (req->protocol == PROTO_HTTP)
return httpCachable(request, method);
if (req->protocol == PROTO_FTP)
return ftpCachable(request);
if (req->protocol == PROTO_GOPHER)
return gopherCachable(request);
if (req->protocol == PROTO_WAIS)
return 0;
if (req->protocol == PROTO_CACHEOBJ)
return 0;
return 1;

No. No firewalls at all. And just one parent (no neighbour).
