German carrier T-Mobile modifies web sites on transmission

Traditionally, the idea of a network service provider is the transmission of data packets – whatever in it, the carrier is not concerned. In fact, Austrian law even acknowledges this fact specifically…which is quite a feat.

Unfortunately, T-Mobile of Germany seems to have found a way to fuxate even something as simple as serving TCP/IP packets. HagensTechiBlog reports that the operator modifies HTML data, packing external CSS files into the HTML file.

The damages of this process are obvious: not only is caching eliminated, it furthermore makes page rendering slower as the whole CSS has to be downloaded before HTML arrives.
