HTTPS -> HTTP redirect?

[Scott Lewis]

Hi, I am working on a project that uses OAI PMH, and recently some of our tests have been failing, giving the reason of a "forbidden" redirect (probably forbidden by the library as a security feature).

The test is trying to open the URL

https://www.openarchives.org/OAI/2.0/

but that URL seems to have a "303 See Other" response which points to

http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd

The code used to open the URL apparently doesn't like the "https" to "http" redirection.  I note that the latter URL above itself has a "301 Moved Permanently" to

https://www.openarchives.org/OAI/2.0/OAI-PMH.xsd

Did something change in the past day or two?  These tests were running fine as recently as April 16 around noon MDT, and the code hasn't really changed when it started failing.

I saw there was a OAI Website Migration on April 16; could that migration be related to this error?

Thanks in advance!

Hi Scott,

I see the same thing:

```

> curl -I https://www.openarchives.org/OAI/2.0/
HTTP/2 303
date: Thu, 18 Apr 2024 20:03:31 GMT
content-type: text/html; charset=iso-8859-1
location: http://www.openarchives.org/OAI/2.0/OAI-PMH.xsd
server: Apache/2.4.37 (Oracle Linux) OpenSSL/1.1.1k

```

There should not be a redirect from https to http there. I'll let you know when it is fixed.

Cheers,

Simeon
