On my development machine (Win 7 IIS7.5) using IE9, If I browse my bootstrap 3 site using localhost/appname it behaves as expected. If I browse the same app using computer-name/appname its as if I am browsing from a phone (the menu gets tucked under the button to slide out the menu, and the layout generally looks busted, the slide out is mangled too). I know the starting point for bootstrap 3 is mobile first. It looks like the responsive bits to get me back to desktop are not happening when using the computer name in the url.
I did a view source on the IE9 browsing alternatives(localhost|computer-name) and saved them to disk and ran them through a diff tool. No html differences at all. Its the same IE9 browser, the same windows 7 box iis7.5, the same app, the same rendered html, just different url entry. What is really to blame?
This same app works with either localhost or computer-name using firefox, chrome, and safari.
When I post the site to our test server using an alias in the url IE9 is busted there too. This is why I need to figure this out versus being content to just use localhost.
We are behind a proxy server. I can browse external sites that use bootstrap 3 with my IE9 and they look fine.
I've also browsed my dev box with Fiddler open but not seeing anything obvious though it may be there and I just don't know.
