If you create auto generate rss feed true for web browser

Write this code in your .aspx file.

protected void Page_Load(object sender, EventArgs e)

{

Masterpage_MasterPage mastertitel = (Masterpage_MasterPage)Master;

mastertitel.Settitle("Placeads");

mastertitel.Setlinktag("Listaclassified top feeds", "link001", "../xml/top100ads.xml");

}

Write this code in master page.

If the user in session then rss can attach.

public void Setlinktag(string title,string id, string href)

{

HtmlHead headtag = (HtmlHead)Page.Header;

HtmlLink linktag = new HtmlLink();

if (Session["memberid"] != null)

{

linktag.ID = id;

linktag.Href = href;

linktag.Attributes.Add("rel", "alternate");

linktag.Attributes.Add("type", "application/rss+xml");

if (title.Length > 10)

{

title = title.Substring(1, 10);

linktag.Attributes.Add("title", title);

}

else

{

linktag.Attributes.Add("title", title);

}

headtag.Controls.Add(linktag);

}

else

{

linktag.ID = id;

linktag.Href = href;

linktag.Attributes.Add("rel", "alternate");

linktag.Attributes.Add("type", "application/rss+xml");

if (title.Length > 10)

{

title = title.Substring(1, 10);

linktag.Attributes.Add("title", title);

}

else

{

linktag.Attributes.Add("title", title);

}

headtag.Controls.Add(linktag);

}

}
