Browser Capabilities Project. Browser Capabilities Project. Flameeyes's Weblog. You might remember that some time ago I proposed blocking old user agents; while I wasn’t able to get around implementing this idea Typo-side, providing proper warning and interface to the users, the Apache move that followed that allowed me to implement my idea for real using mod_security.
While I think the default ruleset in mod_security is quite anal-retentive and disallows me to post most of my technical blogs (and related comments) by disallowing posting strings like /etc, the thing is tremendously powerful. I’m (ab)using it to stop requests hitting Typo for PHP pages (the server is not going to use PHP any time soon), which together with mod_rewrite reduce the load on the server itself.
To implement my idea (which is actually live on this blog for quite a while and refined further today), I first observed the behaviour of most spam comments, it turned out that I could identify some common patterns which really made it easy to write some rules. SecRule REQUEST_PROTOCOL "! Object detection. Page last changed today Fairly soon you will notice that certain features of JavaScript do not work in certain browsers.
If you want to use an advanced bit of script, you first have to check whether a browser supports the objects you want to use. This page explains how to do it. If you want to know whether the browser that views your page supports certain objects you want to use in your code, you should never EVER use a browser detect. Sure, you know that this–and–that browser will support your code while such–and–so browser won’t. While browser detection works well enough for 90% of your visitors, some obscure browsers won't be treated correctly and browsers that appear after you've written the page may not be adequately covered either. An old case study will clarify things. It is a well known fact that IE 3 does not support the document.images array that is vital for a mouseover script. However, on most OS's Netscape 2 doesn't support document.images either.
If (window.focus) List of Mobile User Agents - Mobile-Phone-Specs.com. Mobile detection for coldfusion. User agent. User agent identification[edit] In HTTP, the User-Agent string is often used for content negotiation, where the origin server selects suitable content or operating parameters for the response.
For example, the User-Agent string might be used by a web server to choose variants based on the known capabilities of a particular version of client software. The User-Agent string is one of the criteria by which Web crawlers may be excluded from accessing certain parts of a Web site using the Robots Exclusion Standard (robots.txt file). Possible privacy issue[edit] As with many other HTTP request headers, the information in the "User-Agent" string contributes to the information that the client sends to the server, since the string can vary considerably from user to user.[3] Format for human-operated web browsers[edit] The User-Agent string format is currently specified by Section 14.43 of RFC 2616 (HTTP/1.1). Product name and version (WikiBrowser/1.0)Layout engine and version (Gecko/1.0). Detecting phone type with ColdFusion.
Mobile Browser ID Strings (a.k.a. User Agent ID) The non-mobile stuff is here (hint: you get jerked back by the power cord after 3 feet and your arms start to ache after 10 minutes with non-mobile stuff) or click on any right menu link for the browser/section.
We started these pages with four strings because we had never seen a comprehensive list anywhere. Nominally RFC 1945 and RFC 2068 define them (get RFCs) but only as an afterthought (the RFCs define HTTP 1.0 and 1.1). Browser IDs, more correctly User Agent IDs, appear, among other places, as the environmental variable HTTP_USER_AGENT in Apache. You need this information to make the fewest checks possible for the browser environment or to optimise the display or ... to know who and what is crawling around your site. And if you want to check your browser string use our cheap trick page. New Stuff: It's been a loooong time since we did an update. Department of useless stuff: Anyone know the difference between Open Mini and Mobile...no it's not the beginning of a joke. Notes: Dolphin. I am looking for the equivalent of this code in classic asp Microsoft IIS Web Server and ASP.NET forum at WebmasterWorld.
