I've been tasked to maintain a PHP website with a function which automatically generates RTF files and provides a link to download. Each time the previously generated file is overwritten by the new one.

My home page is largely the same for all users, which makes it a candidate for page caching. however, there are a couple of things that are user specific. For example, there is a nav item that is only shown for logged in users and there is a link like logout, my profile etc, generated for specific users. Do I have to use fragment cachi...

These reports will contain charts, which can also be generated on the fly. Because these charts contain sensitive information, using a 3rd party chart API (ie: Google Charts) is out of the questi...
I have some custom table view cells that takes a while to draw, so the first time you scroll it's not very smooth. After the first scroll, all the views are cached and the scrolling is very smooth. So what I'm wondering is if I could draw all the cells and cache them before the table view is shown and how I would do that. Would there be...

I have a dynamically-generated javascript file that I want to ensure is NEVER cached by the browser. My current method is to simply append a (new) guid to the url in the script tag on each page view. For example: <script type="text/javascript" src="/js/dynamic.js?rand=979F861A-C487-4AA8-8BD6-84E7988BD460"></script> My question is...i...

Does anyone know a common workaround to this? ...
I need to load a couple thousand records of user data (user contacts in a contact-management system, to be precise) from a REST service and run a seach on them. Unfortunately, the REST service doesn't offer a search which meets my needs, so I'm reduced to just loading a bunch of data and searching through it myself. Loading the records i...
