I have a button at a visualforce page, after users click that button, the PageReference will point to an external URL, now it opens as a full window. What I want is to open it at the current visualforce page panel, can I do that?

thanks,

I am using HTTP class to post a xml file to a site, and everything works well but getting this error message "System.CalloutException: Read timed out" at res = http.send(req); at the first try of the day, then I won't see this message again. If I am not running the code for quite a while, then it may come up again, is there anybody experiencing the same thing?

Thanks,

req.setEndpoint(url);

...

res = http.send(req);

res = http.send(req);

Is there a better way creating the xml file on the fly, instead of kind of hard-coding by using XmlStreamWriter?

thanks.
