Public yum repositories return 200 OK for nonexistent content instead of 404

[paralllax]

Hello,

As it currently is, the repository will return a 200 OK for any request, whether it exists or not, then serve a page displaying a 404, instead of servicing the return code. When mirroring the repository it causes issues when searching for a treeinfo file or similar as it sees the 200 OK and attempts to pull - then fails as it isn't present.

$ curl -s "http://exablaze.com/downloads/yum/redhat/el7/x86_64/repodata/treeinfo" -ILk | grep HTTP
HTTP/1.1 302 Found
HTTP/1.1 302 Found
HTTP/1.1 200 OK
$ curl -s "http://exablaze.com/downloads/yum/redhat/el7/x86_64/repodata/treeinfo" -Lk | pup 'title:contains("404") text{}'
Exablaze - Error 404 - Page Not Found

I'm unsure if this is the best place to reach out regarding the issue, let me know if this should be posted elsewhere! Thank you
