📄 Description

Summary

Extends the fix from PR #23856 to all streaming response paths in that forward upstream headers to the client. The original PR only addressed , but , , and can also trigger when hop-by-hop headers like , , , and are forwarded through a different HTTP stack.

Changes

  • Added constant (matching the pattern already used in )
  • Added helper function
  • Applied the helper to all four SSE streaming paths in :
    1. (line ~1201)
    2. (line ~1288)
    3. (line ~1404)
    4. (line ~1510)

Testing

The fix follows the same pattern as the existing fix in which correctly strips these headers. All four code paths now use the same filtering approach before passing headers to .
