Branching off from this link it seems that Request.ServerVariables('SCRIPT_NAME') doesn’t return anything. I’ve just set up a simple loop to see if anything comes out at all but with no luck. Any ideas?

For Each s As String In Request.ServerVariables    Label1.Text += s Next

ServerVariables brings back a list of Strings in key->value form as defined in System.Collections.Specialized.NameValueCollection

EDIT: It seems to be a problem with getting the ServerVariables from a page using master pages. In my code behind model I’m defining the following:

Public Partial Class Test     Inherits System.Web.UI.Page    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load     Response.Write(Context.Request.ServerVariables('SCRIPT_NAME'))   End Sub End Class

This doesn’t work, quite simply. If I enter the code within the Page_Load event within the .aspx page, however, by doing the following:

<% Response.Write(Context.Request.ServerVariables('SCRIPT_NAME')) %>

Then it works fine. Any ideas as to why that’s happening?

  1. Are you sure you’re not getting this back?

    Using Response.Write from the code behind (either in the page or the master page) will output the string at the top of the page (usually), before the rest of the HTML, etc, which is probably not where you’re expecting to see it.

    I put a literal control on a master page, before the content placeholder:

    On Master: <asp:Literal id='LiteralMaster' runat='server'></asp:Literal>

    And then setting it’s Text property in the master page’s Page_Load event to:

    LiteralMaster.Text = Context.Request.ServerVariables('SCRIPT_NAME')

    I also added a literal control in the content placeholder on a page that used this master page:

    On page: <asp:Literal id='LiteralPage' runat='server'></asp:Literal>

    And in the page’s Page_Load event I had the following:

    LiteralPage.Text = Context.Request.ServerVariables('SCRIPT_NAME')

    Which resulted in:

    On Master: /LittleTest/UsingMaster.aspx
    On page: /LittleTest/UsingMaster.aspx

    Modifying my page’s Page_Load event to become:

    LiteralPage.Text = Context.Request.ServerVariables('SCRIPT_NAME') Response.Write('From response.write: ' &   Context.Request.ServerVariables('Script_Name'))

    Resulted in the following display in my browser:

    From response.write: /LittleTest/UsingMaster.aspx
    On Master: /LittleTest/UsingMaster.aspx
    On page: /LittleTest/UsingMaster.aspx

    However, the html looked more like:

    From response.write:/LittleTest/UsingMaster.aspx  <!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Transitional//EN'          'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'>  <html xmlns='http://www.w3.org/1999/xhtml'>   <head>     <title></title>   </head>   <body>     <form name='aspnetForm'        method='post' action='UsingMaster.aspx' id='aspnetForm'>       <div>         On Master: /LittleTest/UsingMaster.aspx         <br />         On page: /LittleTest/UsingMaster.aspx       </div>     </form>   </body> </html>

    Edit to respond to comment

    You are assigning the string representation of a NameValueCollection element to the contents of your label, this is just the NAME, not the combination of the NAME and the VALUE

    Try the following:

    For Each s As String In Request.ServerVariables   Label1.Text += s & ': ' & Request.ServerVariables(s) Next

    For more info, take a look at the MSDN docs:

    HttpRequest.ServerVariables
