Shouldn't the PUT API requests respect the "If-Unmodified-Since" header?
A sample workflow
- Make a GET request on a resource, an Issue for example
- Do some data manipulation and calculate something
- Make a PUT request on the same resource, trying to set some attributes
How can I be sure that my PUT request, on step
#3, will not "clobber" a resource attribute that was set by another user while I was doing my calculations while in step
I would expect that the
updated_at timestamp from the resource I GET, from step
#1, if used as a
If-Unmodified-Since header (with the timestamp,properly formatted) in the PUT request, in step
#3 would result in a 403 (maybe?) if the resource has been modified sometime between step
In my example (in the current hosted version of Gitlab) passing a header with a ridiculously old date
If-Unmodified-Since: Sat, 29 Oct 1994 19:43:31 GMT while doing a PUT API call on an existing Issue, results in 200 OK status and my Issue being updated.
