My website <a href="http://www.preordertickets.com" rel="ugc">www.preordertickets.com</a>&nbsp;uses javascript and the gd 2 graphics library. &nbsp;The javascript calculates the dimensions to resize the images to based on the user's screen resolution. &nbsp;If you visit <a href="http://www.preordertickets.com" rel="ugc">www.preordertickets.com</a>&nbsp;and then click on the yellow tab that says&quot;tickets&quot; you will notice that the header graphics and the yellow tab graphics are downloaded again. &nbsp;<br />
<br />
I am looking for a way to prevent this re-downloading from happening. &nbsp;I want a way to tell the browser that these images should be stored in cache and do not need to be downloaded again. &nbsp;Thanks in advance to anyone who can help. &nbsp;I know this is a very difficult question.<br />

Allow dynamically resized images to be stored in browser cache

JavaServer Pages (JSP) allow the development of dynamically generated web pages. It uses the Java programming language; JSP pages are translated into servlets at runtime, with each servlet being cached and reused until the JSP is modified. JSP allows Java code to be interleaved with static web markup content, so the resulting page can be compiled and executed on the server to deliver the content.
