Truncating an external iView URL

Hi All,

Requirement : Accessing portal Discussion Group iView from a BSP application ?

We have configured SSO between CRM and Portal . I am using following method to open the discussions group iView externally .

http://<server>:<port>/irj/portal?NavigationTarget=<pcd location of iView>

This is working fine if I access it through a browser.

But as in BSP there is a limit of 255 characters I am not able to pass this long URL to a method .

Does anybody know how to truncate this long URL .

Thanks & Regards,

Amit Kade
