Hi, first i want to say, that my first question i have sent a few hours ago was answered very quickly! Great Support.
Now my shop-sites are crawled I have a nother problem: 
On the category-pages you can select different amount of product shown on one page. the crawler no put the same category with different amounts of products, so that every category is listed 4 times. 
Example:
  <url>
       <loc>http://www.domain.de/category/subcategory:::25_83:9.html?prllset=5</loc>
       <lastmod>2011-02-17T00:47:20+00:00</lastmod>
       <changefreq>daily</changefreq>
       <priority>0.2097</priority>
  </url>
  <url>
       <loc>http://www.domain.de/category/subcategory:::25_83:9.html?prllset=10</loc>
       <lastmod>2011-02-17T00:47:20+00:00</lastmod>
       <changefreq>daily</changefreq>
       <priority>0.2097</priority>
  </url>
  <url>
       <loc>http://www.domain.de/category/subcategory:::25_83:9.html?prllset=20</loc>
       <lastmod>2011-02-17T00:47:20+00:00</lastmod>
       <changefreq>daily</changefreq>
       <priority>0.2097</priority>
  </url>
  <url>
       <loc>http://www.domain.de/category/subcategory:::25_83:9.html?prllset=50</loc>
       <lastmod>2011-02-17T00:47:20+00:00</lastmod>
       <changefreq>daily</changefreq>
       <priority>0.2097</priority>
  </url>
Has anybody an idea how to solve this?
Kind regards 
Marco
