OWSSVR.DLL is used in SharePoint Designer for FP-RPC (Front Page – Remote Procedure Call).Now its getting depricated in each release.

Following are some of dpecricating OLD DLL usage.
1. Returning all data for a SharePoint list, including its XSD - http://[localhost]/_vti_bin/owssvr.dll?Cmd=Display&List={ListGuid}&Query=*&XMLDATA=TRUE

2.Rreturning data of SharePoint list based on a specific view from the list -http://[localhost]/_vti_bin/owssvr.dll?Cmd=Display&List={ListGuid}&View={ViewGuid}&XMLDATA=TRUE

3.Returning List definition - http://[localhost]/_vti_bin/owssvr.dll?Cmd=ExportList&List={ListGuid}

4. Retrieving ONET.XML - http://[localhost]/_vti_bin/owssvr.dll?Cmd=GetProjSchema

5. Retrieving field types - http://[localhost]/vti_bin/owssvr.dll?Cmd=GetProjSchema&SiteTemplate=fldtypes

OWSSVR.DLL workes based on httpget so you can use that in your javascript

<script>
function GetList()
{
// -- getting the filtered lookup
var reqstring = siteName + "/_vti_bin/owssvr.dll?CS=109&XMLDATA=1&RowLimit=0&List=" + lookupListName + "&View=" + lookupViewName;
var req = new ActiveXObject("MSXML2.XMLHTTP");
req.open("GET",reqstring,false);
req.send();
// -- loading response in XML Document
var doc = new ActiveXObject("MSXML2.DOMDocument");
doc.loadXML(req.responseText);
var data = doc.documentElement.childNodes(1);
for (i=0;i<data.childnodes.length;i++)
{
}
}
</script>
