Posted this elsewhere but got no answer so maybe here someone had the same issue before.
Got an email from a friend, asking why my website's HTML content was broken and had me baffled for a while. Following up on the issue I manage to get the HTML code he was getting with his browser. The HTML content was indeed mangled. Initially I assumed he was accessing the server via a proxy but after some investigation I concluded everything was good, there was no "unknown" man in the middle.
So what happened this person was accessing the site using an ISP who provides a wireless service. They are forcing some sort of mini-compression to the images and HTML content downloaded to browsers, to give you a better understanding of what is all about you can search for
bmi_SafeAddOnload
Now the HTML code that was mangled had various resource stylesheets, javascripts etc as part of the HTML page. Under normal circumstances different connections to a server take place to pull in these resources.
But in this case whitespace was stripped and copyright headers of the stylesheets and javascripts were removed the resource files (part of them) were put inside the same page. The ajax scripts were broken so the pages of course did not work as expected. I suspect this happened because the copyright text was presented in the CSS and Javascript files as comments and the whatever filter in use is by the ISP, erases every comment.
So let alone striping the HTML and javascript content breaking pages, they strip out the copyright headers from the stylesheets, html pages, javascripts etc., so a user doesn't know to whom the content belongs to really.
Does anyone has any experience about it or knows if that is illegal?
Just to avoid any confusion this is not related with browser settings or firewalls or router settings. Its how the wireless service is setup and cannot be changed from what I learned. Probably this is not easily visible with a mobile phone but when you use a laptop it is.
