InfoPath Dev

Hi All,

Environment:

Windows server 2008 

Sharepoint 2007 enterprise edition.

Infopath 2007

Issue:

I have created custom workflow in sharepoint 2007 using infopath forms.

1. When I submit to workflow it redirects to login page ( I placed submit button in my infopath forms).

2. When I click on item in the task list, it should go to the custom workflow page to approve or reject instead it gets redirected to the login page. Once I enter the credentials it goes to the workflow page as it should.

Session timeout and membership forms timeout are 60 mins. I made sure that it is not related to session timeout. At the time of sign out no request is sending to the server. suddely its getting signout. I checked in the windows log and sharepoint log but there was no entires related to this issue.

This is not happening for all items but it happens frequently.

Thanks in advance.
