I have a asp.net website in which i check for supported browser.
That is i user
Request.Browser.Browser -- for the browser name
and
Request.Browser.MajorVersion for the browser version
Problem here is browser Safari and Google Chrome show me the same value !!!
That is AppleMAC-Safari(name) and version would be 5..
How do i differentiate between google chrome and safari then ???
Thanks ,
Francis P.
For each browser that Request.Browser.Browser can detect, there must be a *.browser file in C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG\Browsers. Chrome and Safari are missing in version 2 of the .NET framework, but you can download an updated set of browser configurations from codeplex: http://aspnet.codeplex.com/releases/view/41420
There could possibly occur some compatibility issues (since these files are made for .NET 4). In such cases you may have a look at this blog post: http://stephenwalther.com/blog/archive/2010/03/05/use-asp.net-4-browser-definitions-with-asp.net-3.5.aspx

I'm using simple browser made with Qt WebKit.
On a page (running local rails server) I have a link that opens Pdf Previewer (pdf.js). In this .js script I try to open local (rails) url with path as parameter. Path can be local file path or some public url.
example:
http://localhost/documents/preview_file?path=http%3A%2F%2Fmy-domain.s3.amazonaws.com%2F4533902%2Ftest.pdf%3FAWSAccessKeyId%3DAKIAJWDKNPWPFJYREP6Q%26Expires%3D1480381051%26Signature%3DCqfAmGCm7S5lTpQ7pP0U25BqYpE%253D
In case parameter path is public url rails only redirects to this url.
But problem is, that in this browser I get an error (in console):
GET
http://localhost/documents/preview_file?path=http%3A%2F%2Fmy-domain.s3.amazonaws.com%2F4533902%2Ftest.pdf%3FAWSAccessKeyId%3DAKIAJWDKNPWPFJYREP6Q%26Expires%3D1480381051%26Signature%3DCqfAmGCm7S5lTpQ7pP0U25BqYpE%253D
Protocol "" is unknown
I get this error only in this QtWebKit browser, Chrome and Firefox open this link without problem.
Any help appreciated

QtWebKit released with Qt is based on outdated WebKit engine, that does not implement all Web features available in modern browsers. So it is possible that your page is using some of JavaScript features that are not supported.
Please try your page with latest QtWebKit from https://github.com/annulen/webkit/releases/tag/qtwebkit-tp5. It is based on fresh WebKit and may work better with your content. See http://qtwebkit.blogspot.com/2016/08/qtwebkit-im-back.html for more details about what is happening with QtWebKit now.
I have one interesting issue on this project, which is actively using Visual Composer WP Plugin.
When one of my clients tries to view the site on
MacBook Air OS X El Capitan
Safari v. 9.0.1 (11601.2.7.2)
the browser does not show any images on the main page. They are all loaded to the DOM and can be saved and then opened like a separate file, but on the web page it is just an empty space (smth like css {opacity: 0} rule).
I've been looking for some articles on this issue, but most of them refer to official forums and browser settings fixes. But it is not the case, as this client has a complete user experience on other web pages. And I must say it'is working fine on all the other major desktop and mobile browsers.
Update
Tested with
Safari 8.0.4 (10600.4.10.7)
MacBook Pro OS X Yosemite
works like a charm
I have an application that is using GWT 2.0.4 and running fine on IE8 browser. When opened in IE11, it is giving blank page with error message given below.
com.google.gwt.core.client.JavaScriptException : (TypeError) : Object doesn’t support property or method ‘attachEvent’
The exception was thrown because “attachEvent” is a deprecated function used in older versions of Internet Explorer. IE11 uses “addEventListener” method instead of “attachEvent”.
The user.agent value was set to "ie6" so i changed it to "gecko1_8". After changing user agent it opens the application but the data in table(GWT-ext GridPanel) is getting overlapped over one another, scrollbars are missing and the alignment of menu bar is changed.
It is working fine after enabling the compatibility mode. What is the proper workaround to run my app in IE11 ? Do i need to upgrade GWT and if yes then to which version supports IE11? I don't have to use "X-UA-Compatible=IE8" meta tag....Please help
As with anything on the Web, you should always try to run the latest version, because everything changes around your application. 2.0.4 is 5 years old already!
So yes, upgrade to the latest version of GWT (2.7.0 as of today), and when the next version will come (2.8, in a few weeks) try to upgrade as well.
As a workaround, because it works in IE8, you could probably ask IE11 to emulate it using an X-UA-Compatible with value IE=EmulateIE8. But that's only a temporary workaround, as the next version (Edge, coming in Windows 10 to replace IE) will no longer support X-UA-Compatible (except in the Intranet zone). See the warning at the top of the X-UA-Compatible doc and this announcement by Mirosoft. The real solution is to stay up-to-date with GWT versions, just like you stay up-to-date with browser versions.
I note that I cannot be launched on web IE 11 ..
I know that the useragent for IE11 is Trident not MSIE . so I suppose that the reason why I got always notification to install java even its already installed .. but I cannot find temporarily solution for that as guys solve this issue by updating deployJava.js for webstart and by adding "trident" with "msie"...
just note that only windows 7 can install IE11 or its bundled with Windows 8.1 .. you cannot install IE11 or update it to IE11 on windows 8.
again and briefly my questions are :
1- where JavaFX app detect browser agent?
2- is it possible to the modify package that is responsible for that and include jar to project ?
any idea is welcomed ..
Internet Explorer 11 is not a supported configuration for JavaFX in JRE 7.
You can request support for Internet Explorer 11 by filing a feature request in the JavaFX issue tracker. You can link back to this question in your feature request.
I guess what you are saying in your question is that the information Microsoft place in the UserAgent string for IE11 has changed from previous versions and the way to understand the UserAgent string encoded information has changed in IE11 compared to earlier browser releases. These changes mean that the current JavaFX deployment code does not correctly detect it is running in an IE11 environment and perform appropriate operations to enable JavaFX applications to execute in IE11.
I believe that JavaFX packaging code uses a dtjava.js script to detect the target browser. For JavaFX 8 this detection routine is (I believe) the JavaScript detectEnv() method. What you might need to do to get IE11 compatibility is to host your own deployment scripts and replace the dtjava.js in your local deployment scripts with a modified version you have created which is IE 11 compatible (detailed instructions on how to do this are outside the scope of this answer). Even if you do get the dtjava.js script to correctly identify and execute logic for IE 11, there may still be other issues running JavaFX in IE 11 (due to it not being currently a supported deployment platform).
I've made some modifications in dtjava.js and got it to work in IE11
In my case I'm using dtjava.js only for embedding an applet not based in JavaFX, so probably these modifications are not enough to make a JavaFX application run.
I changed the IE detection rule from
ie = isDef(window.execScript);
to
ie = /trident/.test(u);
in detectEnv()
and
if (isDef(d.addEventListener)) {
d.addEventListener("DOMContentLoaded",
invokeCallbacks, false);
}
if (ua.ie && ua.win) {
with
if (isDef(d.addEventListener)) {
d.addEventListener("DOMContentLoaded",
invokeCallbacks, false);
}
else if (isDef(d.attachEvent)) {
in init() function.
Of course, these are hacky changes not very tested (only Explorer 10, 11 and latest FIrefox and Chrome). Follow at your own risk...
i am using Netbeans PHP + Firefox 4 on Windows for my web development.
I've used a common firebug extension called Xrefresh. It was automaticlly refreshing my opened firefox tab everytime change in my projects directory occured, so pressing ctrl+s in netbeans was triggering auto-refresh in the browser. Very comfort way to work with css, almost live preview.
But now since new Firefox and Firebug versions Xrefresh doesn't work anymore and the question is - are therey any good alternatives, or does someone know how to configure Xrefresh now?
Without live preview my development is somehow slower.

This could help you. It refreshes the page via ajax on css save.
There's an automatic refresh-on-change tool for IE. It's called ReloadIt, and is available at http://reloadit.codeplex.com . Free.
Not an add-on to IE, but more of an "adjunct". It does not change the IE install, does not install a BHO or anything like that. So very low-impact installation.
You choose a URL that you'd like to auto-reload, and specify one or more directory paths to monitor for changes. Press F12 to start monitoring.
After you set it, minimize it. Then edit your content files. When you save, the page gets reloaded. like this:
I've managed to keep using xrefresh up until Firefox 9 however I'm not having any luck with version 10.
I've now switched to livereload, they've had a decent Mac version out for a while and a very experimental Windows version has recently been released.
