Get your hands on a brief HTML file with a meta-refresh set to 1 second and containing some JavaScript code. If the JavaScript kicks in, it will quickly modify the URL for the meta-refresh.
This tactic serves as a makeshift approach to graceful degradation, catering to older cellphones with slower internet connections that would struggle with downloading the web application more than once due to poor design choices.
In an ideal scenario, users should only download the non-JavaScript version; however, since it includes script tags, at least one JavaScript file will also be downloaded. The solution lies in deploying unobtrusive JavaScript to rectify the original page.
Considering the potential flaws in the aforementioned design, I recommend utilizing the meta-refresh strategy to introduce a slight delay during downloads, allowing the JavaScript ample time to make necessary adjustments.
An alternative method involves assessing the JavaScript version compatibility by verifying the presence of specific objects (such as <canvas>
) and subsequently redirecting to the appropriate URL based on the findings.
