How long can be URL in Go to URL when calling SSRS report?

Hi

I am facing issues when calling a report using go to URL. I have 6 cascading multiple value parameter in one of my report and from this I am calling another report by passing all these parameters using java script in go to URL option. Since I am passing all these multiple value parameter my report URL is exceeding up to 5000 to 7000 characters long. This is not working at all as max characters in URL are allowed to be 2048.

Is there any work around to pass all these multiple value parameter using go to URL option?

I thought of using Go to report instead but our business is not allowing to this.

Thanks!
