-
- Response.Buffer = True
- Response.ExpiresAbsolute = Now() - 1
- Response.Expires = 0
- Response.CacheControl = "no-cache"
- Response.AddHeader "Pragma", "No-Cache"
Copy the code
2. Add it to the html code
3. Pass a parameter to the page when re-calling the original page Href="****.asp?random()"
The first two methods are said to fail sometimes, while the third method is to pass a random parameter when jumping!
Because aspx's cache is related to parameters, if the parameters are different, the cache will not be used, but the page will be regenerated. Passing a random parameter each time can avoid using the cache.
This only applies to asp&asp.net
4. Disable caching in jsp pages:
-
- response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
- response.setHeader("Pragma","no-cache"); //HTTP 1.0
- response. setDateHeader ("Expires", 0); //prevents caching at the proxy server
add these codes in the middle of :
-
- <%
- response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
- response.setHeader("Pragma","no-cache" ; replace("WebForm1.aspx");
The parameter is the page to be covered.
-
- The principle of replace: Use the current page to replace the page specified by the replace parameter.
This prevents the user from hitting the back key.
-
javascript script, examples are as follows:
a.html
a
b
Copy code
b.html
b
a
Copy code
6. PHP disable page caching
# Let it "expire" in the pastheader("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); # Always modified header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");# HTTP/1.1 header("Cache-Control: no-store, no-cache, must-revalidate"); header("Cache-Control: post-check=0, pre-check=0", false); # HTTP/1.0 - header("Pragma: no-cache");
