Boost is one of the most widely used Drupal modules designed for static page caching. It creates html files for Drupal pages.When an anonymous user visits the page for the first time, boost generates an html page and then serves the html directly to the other anonymous users of the site, till the page cache expires, which increases the performance of the site for anonymous users, as everything is handled at the Apache level. Nevertheless, there will be situations where boost might not cache a page. Read on to know if you have faced a similar problem.

Often, when you update styles or images on your website, the users of your web application might still get the old logo or style. This is because the browser caches the resources on your web application. Hence, when the user tries to access the application, it will be loaded from the local computer, not from the server. Here is a solution for this issue. Read on to know how to expire cached resources on your browser from your web application itself.

One of our clients sent us images they want to put in the website as pdf files. There were 100 files each containing a single image. Opening each of these in gimp and then saving it as pngs was a nightmare. For all such situations, ImageMagick is there for your rescue. With mogrify - a command utility available in the ImageMagick package, bulk converting all these pdf files to png was child's play.

As a Drupal developer, when we get an error, we may want to know the functions that are called before the system called the function where we get the error. In this case, views_trace() function comes to your help. This function is available if Drupal’s Views module is installed and enabled.

The simplest debugging tool used most often by a programmer is a print statement, which when placed, used wisely can bring out the weak points of any giant bug.

While developing Drupal sites, sometimes we may wish to see whether our function is getting called or whether we reach a point or not in the execution path. Usually the dpm() or print_r() functions comes handy in the case, but sometimes, we may not be able to see the debug messages printed due to page redirection just after our print.
