 For a proxied install you would (continuing the example) do:
 
-  http://sowemustthink.space/greenstone3-lod/greenstone/query?query=select+*+where+%7B+%3Fs+%3Fo+%3Fp+%7D+limit+100&output=text&stylesheet=
-  
+http://sowemustthink.space/greenstone3-lod/greenstone/query?query=select+*+where+%7B+%3Fs+%3Fo+%3Fp+%7D+limit+100&output=text&stylesheet=
+
+
+Factoring in these details, it is possible to setup a transform/page/sparql.xsl page in Greenstone3 this is fully operational,
+even in the ReverseProxying situation.
+
+One key step in sparql.xsl is to updated the form input argument for 'stylesheet' to specify the proxied prefix URL:
+
+  stylesheet=/greenstone3-lod/xml-to-html-links.xsl
+  stylesheet=%2Fgreenstone3-lod%2Fxml-to-html-links.xsl
+
+
+When asking for the SPARQL XML result to be transformed to html-links, the hyperlinks in the page generated
+also need some tweaking.  The Greenstone3 sparql.xsl page helps plumb the static files used back to the
+/greenstone3-lod/ url, but inside 'xml-to-html-links.xsl' this sets another 'stylesheet=' argument that
+needs to be updated to the ReverseProxy setup
+
+
+    <a href="?query={$query}&amp;output=xml&amp;stylesheet=%2Fxml-to-html-links.xsl">
+->    
+    <a href="?query={$query}&amp;output=xml&amp;stylesheet=%2Fgreenstone3-lod%2Fxml-to-html-links.xsl">
+
+You might need to reload the xml-to-html-links.xsl file in the browser if it has been cached before the change
