获取URL:  
   1、通过ASP.NET获取  
   如果测试的url地址是http://www.test.com/testweb/default.aspx,   结果如下：  
    
   Request.ApplicationPath:                                 /testweb  
   Request.CurrentExecutionFilePath:               /testweb/default.aspx  
   Request.FilePath:                                               /testweb/default.aspx  
   Request.Path:                                                       /testweb/default.aspx  
   Request.PhysicalApplicationPath:                 E:\WWW\testweb\  
   Request.PhysicalPath:                                       E:\WWW\testweb\default.aspx  
   Request.RawUrl:                                                   /testweb/default.aspx  
   Request.Url.AbsolutePath:                               /testweb/default.aspx  
   Request.Url.AbsoluteUrl:                                 http://www.test.com/testweb/default.aspx  
   Request.Url.Host:                                               www.test.com  
   Request.Url.LocalPath:                                     /testweb/default.aspx    
    
   2、通过JS获取  
    
   <table   width=100%   cellpadding=0   cellspacing=0   border=0   >      
   <script>        
   thisURL   =   document.URL;  
   thisHREF   =   document.location.href;    
   thisSLoc   =   self.location.href;        
   thisDLoc   =   document.location;        
   strwrite   =   "<tr><td   valign=top>thisURL:   </td><td>["   +   thisURL   +   "]</td></tr>"strwrite   +=   "<tr><td   valign=top>thisHREF:   </td><td>["   +   thisHREF   +   "]</td></tr>" strwrite   +=   "<tr><td   valign=top>thisSLoc:   </td><td>["   +   thisSLoc   +   "]</td></tr>" strwrite   +=   "<tr><td   valign=top>thisDLoc:   </td><td>["   +   thisDLoc   +   "]</td></tr>" document.write(   strwrite   );    
   </script>    
   thisDLoc   =   document.location;   <BR>      
   thisURL   =   document.URL;   <BR>      
   thisHREF   =   document.location.href;   <BR>      
   thisSLoc   =   self.location.href;<BR>      
   <script>        
   thisTLoc   =   top.location.href;        
   thisPLoc   =   parent.document.location;      
   thisTHost   =   top.location.hostname;      
   thisHost   =   location.hostname;        
   strwrite   =   "<tr><td   valign=top>thisTLoc:   </td><td>["   +   thisTLoc   +   "]</td></tr>"strwrite   +=   "<tr><td   valign=top>thisPLoc:   </td><td>["   +   thisPLoc   +   "]</td></tr>"strwrite   +=   "<tr><td   valign=top>thisTHost:   </td><td>["   +   thisTHost   +   "]</td></tr>"strwrite   +=   "<tr><td   valign=top>thisHost:   </td><td>["   +   thisHost   +   "]</td></tr>"document.write(   strwrite   );  
   </script>    
   thisTLoc   =   top.location.href;   <BR>    
   thisPLoc   =   parent.document.location;   <BR>      
   thisTHost   =   top.location.hostname;   <BR>      
   thisHost   =   location.hostname;<BR>      
   <script>        
   tmpHPage   =   thisHREF.split(   "/"   );        
   thisHPage   =   tmpHPage[   tmpHPage.length-1   ];        
   tmpUPage   =   thisURL.split(   "/"   );        
   thisUPage   =   tmpUPage[   tmpUPage.length-1   ];      
   strwrite   =   "<tr><td   valign=top>thisHPage:   </td><td>["   +   thisHPage   +   "]</td></tr>"      
   strwrite   +=   "<tr><td   valign=top>thisUPage:   </td><td>["   +   thisUPage   +   "]</td></tr>"        
   document.write(   strwrite   );    
   </script><tr><td>
