Disabling ContextId's?

Hi Guys,

I need to disable the contextId when throwing a ClientSide redirect.

E.g.

http://eworks.wcape.gov.za/testeworks2-reports/rwcgi60?testeworks2-pdf+repor
t=exp_r_1084+p_adviceid=32289&$ctxid=_1058281548048


Need to make a call to Oracle Reports.. and it moans and groans about extra
parameters in the url.
The above url it complains about because of the extra context id
parameter...
Is there any way to disable context id across the application or just for a
single redirect?

Thanx
KD
