请问下列一条语句的含义

<script language="javascript" src="http://www.ecarcool.com/premium/webmain.asp?city=<%=request("paraCity")%>&oldins=<%=request("paraOldIns")%>&InsList=<%=request("paraInsList")%>&inskind=<%=request("chkins")%>&carkind=<%=request("paraCarKind")%>&carsit=<%=request("paraInsSit")%>&carweight=<%=request("paraInsWeight")%>&insa=<%=request("paraInsa")%>&insb=<%=request("insb")%>&cardate=<%=request("paraCardate")%>&insdate=<%=request("paraInsdate")%>&carname=<%=request("paraCarName")%>&insf=<%=request("insf")%>&insl=<%=request("ratel")%>&insm1=<%=request("rateinsm1")%>&surl=<%=request.servervariables("server_name")%>"></script>
src后面那段是啥意思啊？
