    <br /><br /><input type="submit" name="Aceptar" value="Aceptar" class="bot" style="float:left;" />&nbsp;&nbsp;<input type="reset" name="Vaciar Formulario" value="Vaciar Formulario" class="bot" />
</fieldset>
</form>
<?php 
    include("ckeditor.php");
    $CKEditor = new CKEditor();
    $CKEditor->basePath = '/edicion/';
    $CKEditor->replaceAll();
?>
<script>Calendar.setup({inputField:"fecha", ifFormat:"%Y/%m/%d",button:"f_b"});</script>

302 is not an error but a redirect to a temporary location. You could resend the request to the new location received in the response header.
