## Summary We're seeing reports that Sonatype Nexus isn't working with cached data. Users are reporting 304 responses that show "Found modified response..." path in the logs. I can't reproduce this on latest Sonatype Nexus, but my best guess is that there's a 304 response that is failing our validators, and we try to use that as if it's a "complete" response? Closes https://github.com/astral-sh/uv/issues/1754.
