Pragma is an HTTP/1.0 header.Pragma: no-cache is like Cache-Control: no-cache in that it forces caches to submit the request to the origin server for validation, before releasing a cached copy.However, Pragma is not specified for HTTP responses and is therefore not a reliable replacement for the general HTTP/1.1 Cache-Control header. Pragma should only be used for backwards compatibility with. where date is the date in the object's server response header and last_modified is the date in the Last-Modified header.

There are three headers to return when you are returning sensitive information and would like to disable caching by HTTP clients: Cache-Control This response header, introduced in HTTP 1.1, may contain one or more directives, each carrying a specific caching semantic, and instructing HTTP clients and proxies on how to treat the response being. HTTP-based caching respects request Cache-Control directives. The HTTP 1.1 Caching specification for the Cache-Control header requires a cache to honor a valid Cache-Control header sent by the client. A client can make requests with a no-cache header value and force the server to generate a new response for every request.. Always honoring client Cache-Control request headers makes sense if you. Many more directives are available - see the Feature-Policy documentation on MDN for a full list.

To supress caching from the client side: Caching is hard to manipulate, (is it o bug or not) you need to add several lines on the client and server side (although this won't eleminate the problem 100% but will minimise it a lot) <%.. Response.expires= 0 Response.Expires=-1 Response.Expiresabsolute = Now() - 1 Response.AddHeader cache-control.

When the Expires header is already part of the response generated by the server, for example when generated by a CGI script or proxied from an origin server, this module does not change or add an Expires or Cache-Control header Expiration can be set on a per-session, per-URL, or per-request basis, in addition to cache headers (see sections below for usage details). When there are multiple values provided for a given request, the following order of precedence is used: Cache-Control request headers (if enabled) Cache-Control response headers (if enabled Cache-Control.

By default, NGINX respects the Cache-Control headers from origin servers.

You can override these defaults as described in the answers below Caching full pages with response caching. The highest level of caching that we can make use of is caching of the entire page.

A full request history is stored and requests can also be grouped into collections that can be run on multiple devices. Further Reading. I'd highly recommend you simple read through the relevant parts of RFC2616 for further information on HTTP methods, headers and so on. The RFC is well written and fairly easy to understand compared to most Early and Late Processing. mod_headers can be applied either early or late in the request. The normal mode is late, when Request Headers are set immediately before running the content generator and Response Headers just as the response is sent down the wire. Always use Late mode in an operational server. Early mode is designed as a test/debugging aid for developers Glad to see this issue being revived, // disable cache manually and the the real http request invoked instance.defaults.headers['Cache-Control'] = no-cache; I have also tried your solution passing config in single request . but no luck. what will be the solution Hi, I am hoping there is a 'simple' answer for this as I have seen a few complicated answers.

In this article, we'll explain the how the browser uses its cache to load pages faster, which factors determine.
Caching these headers gives two pretty significant benefits: the first is that we improve performance a bit by caching these fields and the file hash, the second is that we reduce the need for the upstream servers to send the full files in the response to the `GET` request. The cache is preserved using the `actions/cache@v2` Action Add headers to pass along additional information about a request or a response, such as how browsers should handle the page and its content (authentication, caching, encoding, etc.).
