Etag value might need to be returned within a double-quote, is it feasible to check if the Etag value returned from NSO is within a double quote ... thanks in advance.
W/Optional 'W/'(case-sensitive) indicates that aweak validatoris used. Weak validators are easy to generate but are far less useful for comparisons. Strong validators are ideal for comparisons but can be very difficult to generate efficiently. WeakEtagvalues of two representations of the same resources might be semantically equivalent, but not byte-for-byte identical. "<etag_value>" Entity tags uniquely representing the requested resources. They are a string of ASCII characters placed between double quotes (Like"675af34563dc-tr34"). The method by whichETagvalues are generated is not specified. Oftentimes, a hash of the content, a hash of the last modification timestamp, or just a revision number is used. For example, MDN uses a hash of hexadecimal digits of the wiki content.
