If it still doesn't work, you can fin the actual files of the tiles on the harddrive of the server and manually delete them, with this last resort, it should work for sure.</div><div><br></div><div>Best,</div><div><br></div><div>Vivien</div></div><div><div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Mar 2, 2015 at 1:57 PM, Ramesh De Silva <span dir="ltr"><<a>desilvarami@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi Paolo,<div><br></div><div>Thanks for the directions.

A nice tool to use to generate the sld for rasters is the SLD4raster<br>
QGIS plugin.<br>
It can even upload the style to GeoServer from QGIS.<br>
