<p>Hi Andrea,</p>
<p>Thanks a lot for the clarification. That's good to know.</p>
<p>I know that both Geoserver and QGIS server have easier ways for filtering, but those are not standardized then.</p>
<p>Thanks,</p>
<p>Andreas</p>

<div dir="ltr">Hi Andreas,
<div>no, I'm afraid not, the WMS specification provided no way to filter, and even the SLD/SLD_BODY parameters are not part of the WMS specification,</div>
<div>but part of the SLD one, which a server might decide to implement, or not</div>
<div> </div>
<div>Cheers</div>

<p>Hi Andrea,</p>
<p>Ah - thanks a lot! This helps.</p>
<p>Is there also a simpler OGC compatible way available to filter away categories in a layer if there is no intent to re-style the categories in a layer?</p>
<p>Thanks,</p>
<p>Andreas</p>

<div>Using &sld=... you should feed it with a URL that the SLD can be downloaded from instead</div>
<div>(none of this is QGIS specific, it's just how the SLD specification says user provided styles should be used).</div>

<p>Hi,</p>
<p>Does QGIS-Server support SLD styles to filter away RULEs in a GetMap Request?</p>
<p>I would assume, yes, but in what encoding would I submit such an SLD in a GET request? I know that one should rather use POST reqests for such long parameters, but for experimenting, it would be ok to use GET.</p>
<p>The idea would be to allow users to enable/disable categories within a given layer.</p>
<p>The WMS client would first request the available rules with a GetStyles command (that part works fine) and would then filter the RULE (strip away the unwanted RULEs) and resubmit the GetMap with an SLD. Does that work with QGIS server?</p>
<p>I know that one can also use the FILTER parameter, but we want to do it in an OGC compatible way, since the client being developed should work with any OGC compatible WMS server.</p>
<p>Thanks for your reply,</p>
<p>Andreas</p>
