How to access HTML Request data

Each Freemarker cloudCMS page has access to pre-defined set of variables. Following are implicit variables available to each page.

wbrequest - This denotes the data included with the HTTP Request.
wbheader - This denotes the data associated with a HTTP Header.
wbsession - This denotes the data associated with a specific session of user.

Note : All this variables are read Only.

"wbrequest" Attributes

wbrequest have two custom attributes "pageName" and "pageGroup" which denotes current requested page. You can access other request parameters using following syntax :

 wbrequest.<varname>

wbrequest["var name"]

For multi-value parameter (like "?id=1&id=2") cloudCMS will set Freemarker sequence with all the values. In "wbheader" all the parameters prefix with "_" are custom variables added by cloudCMS.

Try following example links to see how the request information changes below :
HowTo.accessRequestHeader?myparam=somevalue¶m2=somevalue2
HowTo.accessRequestHeader?xyz=1&xyz=2

Following is the dump of current HTTP Request/Header/Session data :

Loop through all HTTP Request

pageName = accessRequestHeader

pageGroup = HowTo

Loop through all HTTP Header
