I ran into an interesting problem: I need the ability to rewrite the url, with the encoded session information, dynamically, after the page has already been loaded by the browser client. I am opening a new browser window for doing searches, some of the fields on my first page need to be passed along to this secondary page. If I didn't need to pass parameters from my form onto the new window I could just use the rewrite tag. Like this: window.open ('<html:rewrite page="/findRequestedFacility.do"/>', 'provider', 'scrollbars=yes,width=640,height=480,status=yes'); ==================================================================== However, my url needs to look something like this: //Grab a parameter off my form... var lUrl = "/findRequestedFacility.do?FacilityId='" + form.facilityId.value + "'"; //Rewrite the URL...Need Javascript function to do this. lUrl = rewriteUrl(lUrl); //Open the thing. window.open (lUrl, 'provider', 'scrollbars=yes,width=640,height=480,status=yes'); Has anybody written a javascript function to do this?
