we have item forms where people need a long time to fill out. I many cases the form digest timout is reached and the item not saved.
SharePoint writes the log error message
ViewStateLog: Failed to find entry in cache: https://sharepoint/sites/Site1/List1/NewForm.aspx
A solution on this site is to extend the form digest timeout. The question I have is:
- Is extending the timeout a recommended way?
- What is the performance and storage impact when setting the timout to 8 hours
- Are there other recommended ways to extend my viewstate session? (calling document.form.submit() would work, but SharePoint clears the RichText-Fields)
Thanks for suggestions!
