http/1.1 protocol error: HPE_INVALID_METHOD

[liorlevtov]

Description:
I'm exporting legacy service which uses CUSTOM HTTP METHODS XX_IN, YY_OUT which is being used for HTTP polling (the days before WebSockets). does envoy support such a methods?

I'm able to get a page successfully but when using those custom methods I get the following error

my setup is include service (with 1 or 2 instances) and ssl termination.

Custom HTTP methods are not supported.

[alyssawilk]

Looks like a fundamental limitation of http_parser
https://github.com/nodejs/http-parser/blob/master/http_parser.c#L953

Apparently longstanding too, as I see a 5 year old custom patch workaround which was never submitted: https://gist.github.com/indutny/3403029c5815fd0799ee

@AndresGuedez

[moderation]

I added a comment to #5155 (comment) yesterday as it looks like http-parser is going to be deprecated sooner rather than later.
