In ie, the solution to the problem of obtaining data cache from ajax requests is ieajax.
The IE browser will always have some strange problems. For example, by default, an ajaxget request is generally sent.

IE browser will always have some very peculiar problems, for example, in the default case, generally send ajaxget request, IE browser to the server-side request for the first time, get the latest data, if the address and parameters are not numbered, the second and later send the request, it will default to obtain the cached data, Such a problem is a common problem in IE, the General post is considered to be a dynamic access (the browser believes that
The Post method is a bit more complicated than the Get method, because the method needs to put the requested parameters in the body of the HTTP request, so the request body needs to be constructed.Steps:1.

Http-get and Http-post Http-get and Http-post are standard protocols that use HTTP (Hypertext Transfer Protocol) predicates ( predicates refer to the process of returning a true or false evaluation of a conditional expression. the parameter is encoded and passed as a name/value pair, and the associated request semantics are used.
