Javascript: Is Javascript cached when called from the html body?

Problem!

I call the function JS

inside the html body section, the function parameters are collected by parsing EL

inside the function.

For example:

<script type="text/javascript">
    jQuery(window).load(function() {
        loadImage("${expression_language_var_1}", "${expression_language_var2}");
    });
</script>

But it seems that sometimes both parameters are cached and I am getting old information.

Questions!

  • Are script tags inside the html structure cached in the same way as external javascript files that are included in the header?

The problem is the entire HTML page is cached including the script tags that contain your evaluated EL. If you are serving a page with the following headers, the browser should not cache it:

<meta http-equiv="cache-control" content="max-age=0" />
<meta http-equiv="cache-control" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="expires" content="Tue, 01 Jan 1980 1:00:00 GMT" />
<meta http-equiv="pragma" content="no-cache" />


For more details on how these headers turn off caching refer to this answer: Using <meta> tags to turn off caching in all browsers?
