  • Feh nocache: minimize caching effects - GitHub
    The nocache tool tries to minimize the effect an application has on the Linux file system cache This is done by intercepting the open and close system calls and calling posix_fadvise with the POSIX_FADV_DONTNEED parameter Because the library remembers which pages (ie , 4K-blocks of the file) were already in file system cache when the file was opened, these will not be marked as "don't need
  • Is there a lt;meta gt; tag to turn off caching in all browsers?
    I found that Chrome responds better to Cache-Control: no-cache (100% conditional requests afterwards) "no-store" sometimes loaded from cache without even attempting a conditional request Firefox responds better to "no-store" but still sometimes loads from cache if you reload immediately afterwords What a mess! –
  • How do we control web page caching, across all browsers?
    From Microsoft For purposes of backward compatibility with HTTP 1 0 servers, Internet Explorer supports a special usage of the HTTP Pragma: no-cache header If the client communicates with the server over a secure connection (https: ) and the server returns a Pragma: no-cache header with the response, Internet Explorer does not cache the response
  • Cache-Control header - HTTP | MDN - MDN Web Docs
    Adding no-cache to the response causes revalidation to the server, so you can serve a fresh response every time — or if the client already has a new one, just respond 304 Not Modified http Cache-Control: no-cache Most HTTP 1 0 caches don't support no-cache directives, so historically max-age=0 was used as a workaround
  • Why both no-cache and no-store should be used in HTTP response?
    Under certain circumstances, IE6 will still cache files even when Cache-Control: no-cache is in the response headers The W3C states of no-cache: If the no-cache directive does not specify a field-name, then a cache MUST NOT use the response to satisfy a subsequent request without successful revalidation with the origin server
  • Cache directive no-cache | An explaination of the HTTP Cache-Control . . .
    The Cache-Control header is used to specify directives for caching mechanisms in both HTTP requests and responses A typical header looks like this Cache-Control: public, max-age=10 public Indicates that the response may be cached by any cache private Indicates that the response is intended for a single user and must not be stored by a shared cache
  • Cache-Control - Expert Guide to HTTP headers
    This is an artifact of HTTP 1 0, as many implementations did not support the no-cache directive max-stale The max-stale directive is used by a client to indicate that they will accept stale HTTP responses up to a certain number of seconds This differs from max-age, as max-stale begins once the max-age expires Cache-Control: max-stale=<seconds>
  • helmetjs nocache: Middleware to disable client-side caching - GitHub
    This sets three headers, disabling a lot of browser caching: Cache-Control: no-store, no-cache, must-revalidate, proxy-revalidate; Expires: 0; Surrogate-Control: no-store
