If a server responds to a POST or other non-idempotent request with a 303 See Other response and a value for the location header, the client is expected to obtain the resource mentioned in the location header using the GET method; to trigger a request to the target resource using the same method, the server is expected to provide a 307 ...
A query string is a part of a uniform resource locator that assigns values to specified parameters.A query string commonly includes fields added to a base URL by a Web browser or other client application, for example as part of an HTML document, choosing the appearance of a page, or jumping to positions in multimedia content.
The HTTP Location header field is returned in responses from an HTTP server under two circumstances: To ask a web browser to load a different web page (URL redirection). In this circumstance, the Location header should be sent with an HTTP status code of 3xx. It is passed as part of the response by a web server when the requested URI has:
This header field is part of HTTP version 1.1, and is ignored by some caches and browsers. It may be simulated by setting the Expires HTTP version 1.0 header field value to a time earlier than the response time. Notice that no-cache is not instructing the browser or proxies about whether or not to cache the content.

Link Equity Transfer: Search engines typically transfer a majority of the link equity (or “link juice”) from the source URL to the target URL for 301 redirects. [ 6 ] Indexing Delays : There might be a lag before search engines recognize the redirect and update their indexes accordingly.
For a subsequent request that would've included the If-None-Match header, do not send this header with perhaps a random 20% probability. With this probability, if the response returns an altered content but the same ETag as what was previously cached, mark the website as buggy and disable ETag caching for it.
