When you use the dialog mode in Asp.net, you will find that each time the page is opened with the same content, the page content is not refreshed, this is the reason for the cache,

The solution is as follows:

First, ASP. NET clears the page cache.
Response. Buffer = true;
Response. expiresabsolute = system. datetime. Now. addseconds (-1 );
Response. expires = 0;
Response. cachecontrol = "no-Cache ";
Response. addheader ("Pragma", "No-Cache ");

The second method is the HTML method.
<Head>
<Meta HTTP-EQUIV = "Pragma" content = "no-Cache">
<Meta HTTP-EQUIV = "cache-control" content = "no-Cache">
<Meta HTTP-EQUIV = "expires" content = "0">
</Head>

The third is to pass a parameter to the page when calling the original page again: href = "*****. aspx? Random ()"

The last option is to disable caching on the page.

the rational use of cache in Web development can effectively improve the performance of websites. However, in some cases, cache may cause many problems.
For example: the cache may cause repeated data submission, the verification code image cannot be correctly displayed . In this case, we need to disable the page cache function.
our common practice is to send a "no-Cache" command, but we found that this command is valid for IE during actual use, but it is not effective for Firefox because Firefox does not cache HTTPS pages but HTTP pages. This is a bug in Firefox and the solution is simple, instead of No-cache, use no-store to send the no-store and no-Cache commands
Processing Method in Asp.net, add the following Code
response. cache. setcacheability (system. web. httpcacheability. nocache);
response. cache. setnostore ();
