Subject: REGTESTS: filters: Check non-HTX Lua filters in HTTP chains
X-Git-Tag: v3.5-dev9~55
X-Git-Url: https://git.kaiwu.me/?a=commitdiff_plain;h=91d772de3f59e7298c3f2c1d8fd90fc5cd697e01;p=haproxy.git

REGTESTS: filters: Check non-HTX Lua filters in HTTP chains

Configure enabled non-HTX Lua rewrites alongside compatible trace and
bandwidth filters in HTTP mode. Check that neither request nor response
bodies are rewritten and the compatible chain still forwards correctly,
with both instances and legacy declarations.

Reuse the TCP rewrite fixture so the compatibility check complements its
positive TCP payload tests.
