[PATCH pve-manager] api: sdn: dns: fix double slash in delete request

[David Riley]

Fix the deletion request for DNS options which contained a double
slash (//), resulting in a URI like /sdn/dns//<dns>. Even though
the server normalized this and the request succeeded, cleaning it
up avoids potential issues with strict reverse proxies or firewalls.

Thanks for the patch! minor nit about the commit message:

although it's not incorrect that this fixes/removes the double slash
in the delete request, the code change would IMO be better described by:

'remove trailing slash in delete request'

as that is what the code reads as, with extra context as to *why* it
is done in the body, e.g. something like:

"
Fixes delete request containing double slashes (//), resulting in a
URI like `/sdn/dns//<dns>`. Although this gets normalized on the
server, a strict firewall/proxy might cause problems.
"

as a side note: according to RFC 2396, a path may only consist of a
single slash [0]

Re: [PATCH pve-manager] api: sdn: dns: fix double slash in delete request

[David Riley]

Thanks for the feedback. I've just sent a v3 to the list that
incorporates the improved wording and the RFC context.

I missed your earlier response because it was sent to the
list only rather than via reply-all, so I had already
dispatched v2 by the time I saw it. The v3 now
consolidates everything.
