Using RCurl's getForm function, which is the only nice way of passing in GET-parameters, I need to alter some http headers. In getURI, you just pass httpheader = c(Whatever='whatever',...) and it'll work. Unfortunately, that argument seems to be ignored by getForm . How do I set the http headers in a getForm request?

For example the code on the first page: index.php <p><a href="/blank.php?name1=value1&name2=value2">next page</a></p> The second page: blank.php?name1=value1&name2=value2 $name1 = $_GET['name1'] ; $name2 = $_GET['name2'] ; echo $name1 ; echo $name2 ; This way webpages are created on the spot and displayed kind of like a CMS and Iuse this method for all the webpages my site has, but if a user bookmarks a tab they will have out of date information for that webpage because that page content is

I have a JSP that dynamically sets the page header of my application. However, I want to be able to call the REST Service that gets user details based on the system user. I already have the system user value but need to call the backend service to get the details from the database. This is already implemented but I don't know how to setup the JSP to do this.
