I've attempting to use a RESPMOD ICAP in squid to modify the response headers before they get to my user. I am attempting to use the ICAP 206 code to be able to do this. Everything works fine if the response payload is more than the preview that my ICAP takes. But, if the max size of the preview is greater than the size of the response payload, the 206 response does not do anything (and it basically looks like a 204 where I get back the original response without any header modification).
Is this a known fact that if the response is smaller than the max preview size then 206 is not a valid response?
IIRC, there is no such fact. In fact, 206 works in Preview by default (and can work outside of Preview after additional signaling from the ICAP client):
> draft-icap-ext-partial-content-07.txt:
Partial Content feature is limited to ICAP Preview by default. Similar to ICAP 204 (No Content) responses, an ICAP client may enable Partial Content responses outside of Preview by sending "Allow: 204, 206" REQMOD or RESPMOD header.
I can't find evidence for that in the ICAP spec, so I am thinking there's a chance I'm doing something else wrong?
It could be a Squid bug or your ICAP service could be doing something wrong. Consider posting a [link to] compressed Squid cache.log with debug_options set to ALL,9 (or, at the very least, "ALL,3 93,9").
