cloud service that we use puts specific header on certain traffic, something like X-BT=Y
It’s not the usual key:value format and it didn’t work when I tried to use it for ratelimiting in istio. My question is format even supported in istio? Thanks
I believe this format may be defining the whole ‘X-BT=Y’ as the header, and not as a header/value pair. I’d try to test for the whole string to see if it’s what happening. If it’s not the desired format (as I suspect) you might try to rewrite it (most likely inside an envoy configuration).
Unfortunately, I do not have the expertise to help you with this rewrite.
Hi, thanks for your reply, it was later clarified that indeed it was meant to be X-BT:Y, apparently nothing extraordinary
