wasmtime / PR #14191 Fix missing Host header in outgoing ... · git-wasmtime

Could you verify that the issue still occurs on latest main without this diff?

I would have expected this to be fixed by https://github.com/bytecodealliance/wasmtime/pull/14167, HOST header should be set unless it's explicitly disabled in the embedding https://github.com/bytecodealliance/wasmtime/blob/e6b33de5139d915a48127fc78b790e2d306cf896/crates/wasi-http/src/p2/http_impl.rs#L80-L82 (this is enabled by default: https://github.com/bytecodealliance/wasmtime/blob/e6b33de5139d915a48127fc78b790e2d306cf896/crates/wasi-http/src/ctx.rs#L218-L221)

FWIW,
$ curl -sL https://github.com/bytecodealliance/wasmtime/pull/14191.patch | git am -3
$ git checkout e6b33de513 -- crates/wasi-http/src
$ cargo test -p wasmtime-wasi-http
passed for me, so it does not look like the test reproduces an issue currently present on main

Right, I wrote it on top of v48.0.0 , and then just rebased on latest main, sorry for the noise.
