what performance problems are you having? How do you know caching a style
sheet will improve performance? Have you figured out where the bottle neck
is? In short, I do not believe caching a style sheet will help you.

I have no clue as to what you are doing with this style sheet, but if
you are not doing anything with it using ASP.NET is it utterly pointless
to cache it. Stylesheets are dealt with client-side, and most browsers
cache them automatically (client-side).

I assume that you are refering to an XSLT stylesheet since you are
transforming it?  You can try caching the         XmlDocument in your pages
Cache[] or Application[] object (example below). I am not sure if this is
thread safe?  If it is not try storing the text(InnerXML) instead of the
object.

  XmlDocument xslt = new XmlDocument();
  xslt.InnerXml =
   @"<?xml version='1.0' encoding='utf-8' ?>
   <xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'>

   <!-- root template -->
   <xsl:template match='/'>
    <xsl:apply-templates/>
   </xsl:template>

   <!-- root template -->
   <xsl:template match='contact'>
    <xsl:value-of select='@firstname'/><xsl:text> </xsl:text><xsl:value-of
select='@lastname'/>
   </xsl:template>

   </xsl:stylesheet>";
  Cache["xslt"] = xslt;

transformations.
