Jesper Brix Rosenkilde	6c38ae7381	reverseproxy: Add valid Upstream to DialInfo in active health checks (#6949) ... Currently if we extract the DialInfo from a Request Context during an active health check, then the Upstream in the DialInfo is nil. This PR attempts to set the Upstream to a sensible value, based on wether or not the Upstream has been overriden in the active health check's config.	2025-04-15 08:44:53 -06:00

Matthew Holt	238f1108e6	reverseproxy: Revert #4952 - don't ignore context cancellation in stream mode ... i.e. Revert commit f5dce84a7028d1b116db7fead27ff8b2506baf78 Two years ago, the patch in #4952 was a seemingly necessary way to fix an issue (sort of an edge case), but it broke other more common use cases (see #6666). Now, as of #6669, it seems like the original issue can no longer be replicated, so we are reverting that patch, because it was incorrect anyway. If it turns out the original issue returns, a more proper patch may be in #6669 (even if used as a baseline for a future fix). A potential future fix could be an opt-in setting.	2024-11-12 13:43:34 -07:00

Jens-Uwe Mager	2bb2ecc549	reverseproxy: Change errors writing the response to warning. (#6532) ... Most of the errors that can be seen here are write errors due to clients aborting the request from their side. Often seen ones include: * writing: ... write: broken pipe * writing: ... connection timed out * writing: http2: stream closed * writing: timeout... * writing: h3 error... Most of these errors are beyond of the control of caddy on the client side, probably nothing can be done on the server side. It still warrants researching when these errors occur very often, so a change in level from error to warn is better here to not polute the logs with errors in the normal case.	2024-08-21 11:39:20 -06:00

Matthew Holt	d93e027e01	reverseproxy: Reuse buffered request body even if partially drained ... Previous commit only works when the backends don't read any of the body first.	2024-04-22 15:22:50 -06:00
Matthew Holt	613d544a47	reverseproxy: Accept EOF when buffering ... Before this change, a read of size (let's say) < 10, into a buffer of size 10, will return EOF because we're using CopyN to limit to the size of the buffer. That resulted in the body being read from later, which should only happen if it couldn't fit in the buffer. With this change, the body is properly NOT set when it can all fit in the buffer.	2024-04-22 13:12:10 -06:00
