Does this work:

<Rule>
                <MaxScaleDenominator>1e4</MaxScaleDenominator>
                <Name>name</Name>
                <Title>title</Title>
                <Abstract>Abstract</Abstract>
                               <PointSymbolizer>
                    <Graphic>
                    <Mark>
                        <WellKnownName>circle</WellKnownName>
                        <Fill>
                            <CssParameter name="fill">
                                <ogc:Literal>#FFFFFF</ogc:Literal>
                            </CssParameter>
                        </Fill>
                        <Stroke>
                            <CssParameter name="stroke">
                                <ogc:Literal>#000000</ogc:Literal>
                            </CssParameter>
                            <CssParameter name="stroke-width">
                                <ogc:Literal>1</ogc:Literal>
                            </CssParameter>
                        </Stroke>
                        </Mark>
                        <Opacity>
                            <ogc:Literal>1.0</ogc:Literal>
                        </Opacity>
                        <Size>
                            <ogc:Literal>4</ogc:Literal>
                        </Size>
                                               </Graphic>
                </PointSymbolizer>
            </Rule>

I really want to not show certain layers until the user has zoomed in so far. But it seems to have no effect.

I've heard reports of success, though perhaps the reprojection stuff
could throw it off. Maybe try 1000 instead of 1e4? And do a
MinScaleDenominator as well? And try getting the map request in the
same coordinate system that it's stored in...

I am facing the same problem with GS 1.3.0 beta4 : it seems that the
Min/MaxScaleDenominator is not taken into account (enclosed sld with Min/Max,
GetMap requests and snapshot for the request where the first image should be
blank, but in fact is not). The test involves no reprojection...
