How to get browser information in JSP?

Question

How do you get IP client and browser information using JSP?

Answer 1

For part of the browser, you need to analyze the User-Agent reqeust section.

String browserType = request.getHeader("User-Agent"); 

There you will find relevant information ...

Answer 2

The following jsp will print your ip address and user agent:

 Your user-agent is: <%=request.getHeader("user-agent")%><br/> Your IP address is: <%=request.getRemoteAddr()%><br/> 

To find out which browser and / or OS the user is using, analyze the header of the user agent.

For example:

 <% String userAgent = request.getHeader("user-agent"); if (userAgent.indexOf("MSIE") > -1) { out.println("Your browser is Microsoft Internet Explorer<br/>"); } %> 

For a list of user agents, see here .

Answer 3

ServletRequest.getRemoteAddr () or X-Forwarded-For if you think you can trust it.

What browser information? Request headers will have a User-Agent.

Answer 4

 String browser=request.getHeader("user-agent"); String browsername = ""; String browserversion = ""; String[] otherBrowsers={"Firefox","Chrome","Chrome","Safari"}; if(browser != null ){ if((browser.indexOf("MSIE") == -1) && (browser.indexOf("msie") == -1)){ for(int i=0; i< otherBrowsers.length; i++){ System.out.println(browser.indexOf(otherBrowsers[i])); browsername=otherBrowsers[i]; break; } String subsString = browser.substring( browser.indexOf(browsername)); String Info[] = (subsString.split(" ")[0]).split("/"); browsername = Info[0]; browserversion = Info[1]; } else{ String tempStr = browser.substring(browser.indexOf("MSIE"),browser.length()); browsername = "IE" browserversion = tempStr.substring(4,tempStr.indexOf(";")); } } 

Answer 5

Here you can find getRemoteAddr (), which

Returns the full name of the client or last proxy that sent the request

... and with this you can (possibly) get a browser

 request.getHeader("User-Agent") 

Answer 6

You can get all the information that the client is ready to provide you through HTTP headers. Here is their complete list.

To access the header in a servlet or JSP, use:

request.getHeader ("header-of-what-you-want");
