The returned data of Ajax calls will be cached, and static html is called. Even if HTML is modified, ie may display it with the original data. Firefox can display new data normally.

Solution:

In prototype get, Set

Pars = "Mod = readarticle & FID = '+ $ F ('fid') +' & Rand = '+ math. Random ();
You can use the methods provided by Java to set HTTP header information in JSP or servlet.
Response. setheader ("Pragma", "No-Cache ");
Response. setheader ("cache-control", "No-Cache ");
Response. setdateheader ("expires", 0 );
Use HTML tags as follows:
<Head>
<Meta HTTP-EQUIV = "Pragma" content = "no-Cache">
<Meta HTTP-EQUIV = "cache-control" content = "no-Cache">
<Meta HTTP-EQUIV = "expires" content = "0">
</Head>
