Hi Antony,
Correct, the kid contacts the parent that is getting a 504 and replies the
same to the kid. That's why I suspect the parent tries to download by itself
instead replying to the kid it does not have the object so the kid should do
a fresh download from internet.
examples:
TCP_MISS/504 708 GET http://w.sharethis.com/button/buttons.js -
CD_SIBLING_HIT/x.x.x.x
TCP_MISS/504 708 GET http://www.googletagmanager.com/gtm.js?id=GTM-NNVXD6 -
CD_SIBLING_HIT/x.x.x.x
TCP_MISS/504 478 GET http://dl4.offercdn.com/2613/styleVideo.css -
HIER_NONE/-
TCP_MISS/504 708 GET http://www.indianrail.gov.in/seat_Avail.html -
CD_SIBLING_HIT/x.x.x.x
etc...
The kid receives these answers and does nothing more, the result is the
browser (client) does not have all the objects for a correct page...
Sometimes, the page is blank because a js script, css, etc... is missing.
There are 2 squid, sibling each of them.
Squid1 (10.1.1.1):
cache_peer 10.1.1.2 sibling 8182 8183 proxy-only no-tproxy
Squid2 (10.1.1.2):
cache_peer 10.1.1.1 sibling 8182 8183 proxy-only no-tproxy
Both are in tproxy (settings from the Squid wiki), ICP is enabled with each
squid.
if you need more details, feel free to ask
Bye Fred
