forcing report to refresh

I have a RS report that I am integrating in to an ASP web site. I have
a menu page that gathers some user parameters (report dates etc) and
then opens the report in a new browser window, passing the user
parameters as querystring variables. I have noticed that the report
does not refresh if you use the same parameters twice in a row. For
example, I opened the report, tweaked the underlying data then ran it
again with the exact same parameters. The report did not channge. It
did change when I hit the refresh button in the report itself though. I
would prefer if my users did not have to perform this additional step.
Is there a parameter I can pass, or some other way to force this to
refresh every time?I never found a parameter that RS recognizes to automatically refresh
the report. What I ended up doing was to make up my own. Basically, I
pass all the parameters the report takes, plus another querystring
variable I called "GenDate", which contains the current date and time.
Than way the report parameters are always different, so the report
always refreshes. The problem with this is that RS does not like to
receive any parameters that it is not expecting, so I have to add this
parameter to every report. I just add it as a report parameter, but
don't associate it with anything in the recordset.
If anyone knows of a parameter the RS will recognize, please let me
know. For that matter, is there a master list somewhere? I have a few
that RS tacks on automatically (rs:Command=Render, rs:Format=HTML4.0,
rc:Toolbar=True, rc:JavaScript=True, rc:LinkTarget=_top,
rc:Area=Report), but the documentation is rather sparse.|||I finally came across rs:ClearSession=True which appears to accomplish
what I'm after.sql
