user-agent

I want to check the user agent of my client. (If it's possible the browser type/version) But I don't know how do that... Thank you for your help. It is OK, I have find. I use : final HttpServletRequest request =(HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest(); final String userAgent = request.getHeader("user-agent"); System.out.println(userAgent); Thank you for your help. It is sent in the User-Agent http header. HttpServletRequest request = (HttpServletRequest)context.getExternalContext().getRequest(); String userAgent = request.getHeader("user-agent");

I found out that my javascript-intensive web site doesn't work reliably (or at all) in IE9. It works, (usually, but not always) with the compatibility mode meta tag in the header, but I just want to build a page that I know will work well in IE9 and then have the usual page redirect to it when IE9 is detected. The usual page is fine in IE 7 and 8 (and every other browser I've tried it on). Can anyone give me some javascript that will do that? Thank you! Here's my usual page: http://ianmartinphotography.com/test-site/test/ The simplest way would be to use IE Conditionals . Note: IE10 and beyond

I need to check the browser's user-agent to see if it is IE6. However I shouldn't use scriptlets (we have a strict no scriptlets policy) to do this. Currently I use <% String ua = request.getHeader( "User-Agent" ); boolean isMSIE = ( ua != null && ua.indexOf( "MSIE" ) != -1 ); %> <% if( isMSIE ){ %> <div> <% } %> What is the cleanest way to do this using JSTL, EL, etc and not scriptlets? <c:set var="browser" value="${header['User-Agent']}" scope="session"/> Zoltan <c:if test="${fn:contains(header['User-Agent'],'MSIE')}"></c:if> If you are using spring-mobile framework you can use following to

Useragent details are sketchy, or I'm not looking in the right places. What, in terms of a navigator.userAgent.match() , would differentiate between Chrome and Safari on iOS7, iPad or iPhone? var ua = navigator.userAgent; var matches = ua.match(/^.*(iPhone|iPad).*(OS\s[0-9]).*(CriOS|Version)\/[.0-9]*\sMobile.*$/i); if (!matches) console.log("Not what we're looking for."); else { console.log(matches[1]); if (matches[2] === 'OS 7') console.log(matches[2]); else console.log('Not the right version.'); if (matches[3] === 'CriOS') console.log("Chrome"); else console.log("Safari"); } Reference: https

I'm having a problem where users on mobile devices are encountering an error in MVC that does not occur when viewing the site on a regular desktop. I can consistently reproduce the error by using Chrome's developer tools and applying any other UA than the default. The underlying exception thrown is: ArgumentException: Illegal characters in path. at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional) at System.IO.Path.GetExtension(String path) at System.Web.WebPages.DefaultDisplayMode.TransformPath(String virtualPath, String suffix) at System.Web.WebPages

I've just been looking through a website's error_log and one of the error's that has been logged a few times is: [21-Jun-2011 12:24:03] PHP Notice: Undefined index: HTTP_USER_AGENT in /home/ukevents/public_html/lib/toro.php on line 130 The line this pertains to in toro.php is: private function ipad_request() { return strstr($_SERVER['HTTP_USER_AGENT'], 'iPad'); } Is it possible for $_SERVER['HTTP_USER_AGENT'] to not be set by a HTTP request? Maxim Krizhanovsky Yes, it's possible, this a HTTP header sent (or not sent) by client, and you should not rely on it. From php manual: Contents of the
