[squid-users] Re: Do we have an algorithm to define the cachabillity of an object by the request and response?

< stripping the range header <
How often should I say: There is no range header any more ! There was one, a
year ago, may be.
Now the range is within URL !

Real world example, brand new:

1396987801.026 1766 127.0.0.1 TCP_MISS/200 930166 GET

And when this "....range=2789376-3719167...." is more or less random now, no
chance for caching.
(Unless you write very smart code to join/select the pieces, assuming, no
checksum or similar nasty parameters in the URL, too.)

I hope, now it is absolutely clear to you.
