[Koha-devel] Seeking comments on Bug 34745: ThingISBN broken

[David Cook]

In the past, I had this problem with my OIDC implementation. CloudFlare didn't like "libwww-perl/#.###', but it would accept an empty string. So I added $ua->agent(""); and it worked fine after that.

I feel like I've had to do this somewhere else more recently as well but I can't remember where... but I just updated my user agent string and it was all good.

I noticed recently that requests to LibraryThing's ThingISBN service are being blocked. Koha tries to access a url like this:

https://www.librarything.com/api/thingISBN/0439139600

...which opens fine in a browser, but triggers the response "WARNING:
URL Request Failed 403 Forbidden" when Koha tries it.

Koha is currently sending the user agent "libwww-perl/6.52" and if I use Firefox's developer tools to load the page with that set as a custom user agent I get a CloudFlare-generated "access denied"
message.

I see other CloudFlare customers complaining about this, so it may just be a default. Should we ask LibraryThing to change their configuration? Should we send a less obtrusive user agent with the request?
