With cache_analyzer
you can analyze the data which will be written to
the Caching Framework. You can filter it by specific keywords or regular
expressions. You can also enrich the logged data with environment variables
like GET, POST, a Backtrace and much more. Also, you could throw exceptions to
prevent writing invalid cache entries into the Caching Framework.
The initial idea behind this was, that "sometimes" my website showed
empty href
attributes of HTML a
tags. I searched a very long time to find
that error, but without success. I then hooked into the Caching Framework to
protocol everything which matches href=""
. A day later of logging data, I
found the issue and saw that the site was called with an invalid L
parameter.
cache_analyzer
is a debugging tool and should not be part of production
mode forever. As it hooks into the Caching Framework it may slow down your
site. So, please uninstall that extension after you have found your issue.
The recommended way to install the extension is using Composer.
Run the following command within your Composer based TYPO3 project:
composer require stefanfroemken/cache-analyzer
Download and install cache_analyzer
with the extension manager module.
