parse the query string

page = ucase(request.querystring("page")) the page to return
brch = ucase(request.querystring("brch")) the branch is a mechanism to determine the drill down level.
a drill down level is like a view of the report, a new tab
is created to indicate that it is a new view
viewer = ucase(request.querystring("viewer")) this is the viewer that is calling the server
vfmt = ucase(request.querystring("vfmt")) the format that the viewer understands

init = ucase(request.querystring("init")) used to build the frames for the html viewer
tab = ucase(request.querystring("tab")) used to keep track of tabs on drill down.
export_fmt = ucase(request.querystring("export_fmt")) used to specify export format and type.
subrpt = ucase(request.querystring("subrpt")) the out of place subreport coordinates.
