Help! Chart rendering problems (SOAP access)

Good day everyone!
I am displaying a line chart by SOAP access of reporting services. The is
rendered to my aspx page well for the first time, but if I change the
parameters, and call rs.Render, it's supposed to show a different picture,
but it's still showing the same one.
The problem is the picture always have the same name coming from the
streamID, so the IE browser get the same picture from its cache instead of
getting the image from disk.
I tried to change the StreamRoot every time, it works, but it's not what I
want.
So the question is:
Is there a way to have different streamID for a chart everytime you want to
render the chart?
Thanks!Could someone help?
