[GitHub] [trafficserver] paladox opened a new issue #7671: Caching doesn't seem to work
paladox opened a new issue #7671:
URL: https://github.com/apache/trafficserver/issues/7671
We've setup a ats instance that has both port 80 and 443 (one instance). We've configured it to connect to our mediawiki backends that run nginx. We are finding that it's not caching. Or at least sometimes caching intermittently.
Our records.config:

Do we need a ats tls terminator and a ats backend for caching to work or is there something we are doing wrong in the backend?
Here's the response for one site from the backend:

Found the reason! Sorry for wasting your time.
We had wgUseCdn off on the test server as it isn't supposed to go through the cache proxies (ats/varnish).

Weird thing is it take a little while for the below to work before it says "uScRs f p eN:t cCHp s " (as in I have to keep trying until it says cached). But it wont work on any other url.

`cache-control: private, must-revalidate, max-age=0`
- `private` means that caches that are solely dedicated to individuals (like your browser) can cache. This is the biggie -- need to change this to public
- `must-revalidate, max-age=0` ... these mean that the cache could store them, but, need to talk to origin server each and every time to make sure the object can be released. I believe that `no-cache` is the more direct way of indicating this combination. Either way, its a terrible combination for Traffic Server, as it will make any read-while-write (eg request collapsing) requests go in serial.
- There is also an `expires: Sat, 24 Apr 2021 15:34:15 GMT` -- which matches the date, which is also saying the object immediately is stale.
- The origin server also says to vary on encoding (makes sense -- compressed v non-compressed), cookie and Authorization (which will very likely be unique to each user ... perhaps why they put in private). There are settings for the number of variants, but, with a variant per user, it seems like it'd be difficult to choose a reasonably number.
Ideally, the origin server folks would rethink their choices above. Alternatively, you can use the header_rewrite plugin to override their decisions -- remove/replace the headers as you deem necessary.

I can see why it does it now...
```cache-control: s-maxage=18000, must-revalidate, max-age=0```
on one of our mw* servers compared to our test mw* server

`cache-control: private, must-revalidate, max-age=0`
- `private` means that caches that are solely dedicated to individuals (like your browser) can cache. This is the biggie -- need to change this to public
- `must-revalidate, max-age=0` ... these mean that the cache could store them, but, need to talk to origin server each and every time to make sure the object can be released. I believe that `no-cache` is the more direct way of indicating this combination. Either way, its a terrible combination for Traffic Server, as it will make any read-while-write (eg request collapsing) requests go in serial.
- There is also an `expires: Sat, 24 Apr 2021 15:34:15 GMT` -- which matches the date, which is also saying the object immediately is stale.
- The origin server also says to vary on encoding (makes sense -- compressed v non-compressed), cookie and Authorization (which will very likely be unique to each user ... perhaps why they put in private). There are settings for the number of variants, but, with a variant per user, it seems like it'd be difficult to choose a reasonably number.
Ideally, the origin server folks would rethink their choices above. Alternatively, you can use the header_rewrite plugin to override their decisions -- remove/replace the headers as you deem necessary.

I have a theory. You show you are using curl -I... I bet you are seeing it cache after you don't have the -I. (curl -I issues a HEAD request. HEAD requests don't fill the cache -- a GET request is needed to fill. Can you try `curl -o/dev/null -D- --resolve meta.miraheze.org:443:127.0.0.1 https://meta.miraheze.org/wiki/Main_Page` ?

I've run the above many times and it still says cache miss (even ran it without -I and same thing).
(Also ran it with -X GET).
Even tried disabling the lua plugins to see if they were the cause.

can we add support for HEAD to trigger cache saves?

Could it be that it doesn't work in ats 8.0? (We run debian 10 with apache ts 8.0).
But even then it doesn't explain why Main_Page gets cached even though it specified the s-maxage and max-age.
I could only get it to work on Main_Page (and that's only after a while of loading it).

Yeah, s-maxage should take priority on a shared cache. I'll try to look into adding a test, and if it fails, try to figure out why

It is possible that ATS is not distinguishing between "s-maxage=18000" and "max-age=0" correctly. We should create an autest for that case.

I'd alternatively recommend:
- adding this to your .bashrc
alias curlhead="curl -sIXGET"
(curlhead --resolve ... then shows you headers, and doesn't transfer the body to you)
the background_fill feature is meant to continue the request. Its somewhat broken right now. So...
- and
alias curlr="curl -D- -r 0-0"
(0 byte range request -- shows you headers, but, the body is 0 bytes.)
in addition to installing the background_fetch plugin. Your range request will trigger the background fetch plugin to fire, downloading the full object into cache.

[GitHub] [trafficserver] mlibbey edited a comment on issue #7671: Caching doesn't seem to work

I have a theory. You show you are using curl -I... I bet you are seeing it cache after a request that doesn't have the -I. (curl -I issues a HEAD request. HEAD requests don't fill the cache -- a GET request is needed to fill. Can you try `curl -o/dev/null -D- --resolve meta.miraheze.org:443:127.0.0.1 https://meta.miraheze.org/wiki/Main_Page` ?
