Question: How can we use simple friendly URLs such as hxxp://mynginx/hadoop to access the UIs?

Example: http://nginx/app should redirect to http://upstream-server:8088

A:

So, if I understood correctly, you have a location block like this:
location /hadoop {
    rewrite ^/hadoop(.*) /$1 permanent;
    proxy_pass http://hadoop;
}

The rewrite statement above sends a 301 Moved Permanently response back to the browser, with the rules you have written. Therefore the user is redirected to the / URI when you access /hadoop.
Most likely you want this:
location ~ ^/hadoop(.*)$ {
    proxy_pass http://hadoop$1;
}

Here we capture the part after /hadoop into a variable, and then use that variable with the proxy_pass destination.
However, you still need to fix the URLs the Hadoop backend is sending back to the client in its HTML code, otherwise it is not returning URLs with /hadoop prefix.

 Q:

Detect wifi connectivity in c#

I am working on an asp.net (or winforms) app that is supposed to detect wifi connectivity and strength. The intention is to provide the field agents with an indicator that they can connect to our main office
What would I need to detect wifi connectivity?  

A:

You can't do it in ASP.NET.  ASP.NET is a server-side technology which renders client-side browsable code.
In order to do this, you would have to develop something that is embedded in the page (ActiveX, Java, Flash, Silverlight) and even then, you would have to have the appropriate security permissions from the user to access the APIs necessary to access the wifi antenna.

A:

Take a look at WlanEnumInterfaces in the wlanapi.dll.  You will have to pinvoke it from C#.  There is a managed wrapper for it on Codeplex (http://managedwifi.codeplex.com), but I can't vouch for it as I've never used it personally.

 Question: How can we use simple friendly url such as hxxp://mynginx / hadoop to access the UIs? 

 Example: http://nginx / app should redirect to http://upstream - server:8088 

 A: 

 So, if I sympathize correctly, you have a location pulley like this: 
 location /hadoop { 
     rewrite ^/hadoop (. *) /$1 permanent; 
     proxy_pass http://hadoop; 
 } 

 The rewrite statement above transport a 301 Moved Permanently response back to the browser, with the rules you have publish. Therefore the user is redirected to the / URI when you access /hadoop. 
 Most likely you want this: 
 placement ~ ^/hadoop(.*)$ { 
     proxy_pass http://hadoop$1; 
 } 

 Here we capture the part after /hadoop into a variable, and then practice that variable with the proxy_pass destination. 
 However, you however need to repair the URLs the Hadoop backend is sending back to the client in its HTML code, otherwise it is not returning url with /hadoop prefix.
