I am working on a new website and I need to develop something to help user manage technical browsers issues. There are many parameters (8) I need to check and I am wondering if some of those could be checked in-browser, mainly through javascript.
Here’s the list of parameters I need to look about :
- is SSL activated?
- is MSXML activated? (for ajax and based on browser security level according to the notes I have)
- what update version of IE6 is used? (if the user has IE6, he needs at least IE6 SP2)
- what HTTP version is used? (1.1 is required)
(The 4 others (browser name, browser version, javascript and cookies) can be tested with javascript)
So, which of those parameters can be tested in the browser, and how?
If one of the parameters I stated is useless, feel free to point it too (and why!)
I’ve never know the HTTP version used by client ever being an issue.
Your description of ‘is SSL activated’ is probably a server side check, most SSL certificates are compatible with 99.9%+ of browsers so it’s a redundant metric.
The solution for the user being on IE6 is always upgrade your browser.
The only concern I would check for is IE6, maybe even IE7 and have a notification letting them know to upgrade their browser. The other checks are overkill unless you are developing something extremely niche. Browser version can be detected reasonablly reliably with USER_AGENT
