Controlling the cache of a DataGrid

Hi there, I have implemented a virtual-scrolling DataGrid with an underlying QueryReadStore as follows

<span dojoType="dojox.data.QueryReadStore" jsId="logsStore" url="./logs.do" requestMethod="post"></span>
<div class="logsListContainer" style="align: center; width: 100%; height: 100%; border: 0px" >
 <table height="100%" id="logs" jsId="logs" class="soria" dojoType="dojox.grid.DataGrid" store="logsStore" rowsPerPage="20" keepRows="20" autoHeight="20"
  query="{action: 'logsList'}" autoRender="false">

I can see on the server's log that the rows are fetched by bunches of 20, which is a good thing, but it seems that they are kept in cache on the client side because they are never reread. This can be a problem when the number of rows is large. Is there a way to control how many rows are kept in cache? I thought that setting keepRows would do the trick, but obviously it does'nt.
