IE bug Ajax request 304 Solution

After opening the debugging tool, the reason is clear: the Ajax returned result http304... each request is cached, and chrome and other browsers normally return 200.

 

 

[Solution]

Ajax requests under IE are cached Based on IP addresses and request routes, so the simplest method is as follows:

1. When a request is sent, a timestamp or random seed is automatically added at the end of the request link.

As above:/home/getmusic? Id = 1 + timestamp, which can be easily solved

2. Since it is cached, it will not be cached.

Front-end page disable cache: <meta HTTP-EQUIV = "Pragma" content = "no-Cache">

Front-end Ajax disabling Caching:

Cache parameters for Ajax requests: Required Boolean parameters. The default value is true (when datatype is script, the default value is false ). Setting false does not load request information from the browser cache.

Backend:

. Net: Response. cachecontrol = "no-Cache ";

PHP: Header ("cache-control: No-cache, must-revalidate ");

Header ("Pragma: No-Cache ");
