------ Solution --------------------
First, disable caching.
Js control reupdate
Script
// This allows for timely updates.
Document. all ("ImgSrc"). src = "csdn.gif? Id = "+ (new Date (). toString ();
Script
Test it by yourself. it should be okay if the file header output can be controlled by js, but it has not been tested.
