How can I guarantee that the ajax response will be cached?

Question

I want to make an ajax call, but I want to make sure it will be cached. I am using jquery.

Is there any way to make sure that the request remains in the cache for most popular browsers?

Answer 1

With jQuery, you probably want to explicitly add an If-Modified-Since header with a parameter ifModifiedthat is false by default:

$.ajax({
     ...
     ifModified: true,
     ...
});

There is also an option cachethat you will need to force true if your data type is jsonpor script. This is true by default for other data types.

For a description of these options, see jQuery.ajax()docs .
