| Summary | 0004126: Mirror load-balancer doen't return 503 to client when they incur a 503 trying to fetch content | ||||
| Description | It would seem that when there is an issue behind the load-balancer trying to fetch content, the load-balancer returns a 200 response to the client, but with HTML content that says: 503 Service Unavailable No server is available to handle this request. Here is the log entry from our proxy that indicates that the response was a 200: 2023-09-05T13:33:55.220Z|40ca9f5eefc6c659|rocky-vault-proxy||HEAD|http://dl.rockylinux.org/vault/rocky/8.6/PowerTools/x86_64/os/repodata/145d657619670c3d373c5c3b6ec9e8b51b3386da2980b3dc761b7310a190869a-filelists.xml.gz|200|0|0|10442 2023-09-05T13:34:04.007Z|40ca9f5eefc6c659|rocky-vault-proxy||GET|http://dl.rockylinux.org/vault/rocky/8.6/PowerTools/x86_64/os/repodata/145d657619670c3d373c5c3b6ec9e8b51b3386da2980b3dc761b7310a190869a-filelists.xml.gz|200|0|0|8782 The 200 that is between the |…| in the above log entries is the HTTP status code, but the content that was actually received from the above GET was the: 503 Service Unavailable No server is available to handle this request. The problem with all of this is that a client that is going to cache a successful (i.e. 2xx) result is going to cache (and thus serve) erroneous content. If instead the client received the 503 response it would know the fetch was unsuccessful, not cache it and would serve from it's own cache. It would then know to check again for correct content in the near future. | ||||
