[squid-dev] StoeiD and ICAP services callouts, when it happens?

[Eliezer Croitoru]

I tried it both on access logs and store_id_extras.
In the access log I am receiving this:
....ICAP-Header-Test: "Connection: close\r\nDate: Thu, 12 Jul 2018 20:42:04 GMT\r\nEncapsulated: req-hdr=0, null-body=1189\r\nIstag: YTGV-Predictor\r\nService: YouTube GoogleVideo Predictor ICAP serivce\r\n "

But on store_id_extras I am receiving for the same logformat ie
store_id_extras "%adapt::<last_h"
"... -"

Now I'm not sure if I'm doing something wrong or it's something else.
>From the access.log it seems that I am doing things the right way but from the store_id helper "input" it seems that something is wrong.

I tried to add both a custom header to the request with a 204(GET only..) and also tried the same by adding an ICAP response header.
(the ICAP response header was not injected in the output above)

%>ha does not log an ICAP response header. It logs an HTTP request
header. You asked about an ICAP response header.

Bugs notwithstanding, the above should work if your adaptation service
adds an X-Store-ID request header field to the adapted HTTP request. You
can check what headers Squid has for %>ha by specifying %>ha without any
parameters.

Yes, %adapt::<last_h should work for logging the last ICAP response
header. Have you tried specified that logformat code, without any
parameters?


HTH,
