Security Issue while uploading documents to sharepoint library.

Question

Hi All,

          I am getting security issue while uploading documents in a loop base on the logic using console app. After uploading about 100 documents. 

Error: The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again. 

I have already tried with  below options

1)   oWeb.AllowUnsafeUpdates = true;
2)  oWeb.Site.AllowUnsafeUpdates = true;
3)  oWeb.Site.WebApplication.FormDigestSettings.Enabled = false;

None of the work for me.

Immediate help will be greatly appreciated.

Answer 3

Can you please provide what exceptions are getting logged in 14 hive log folder or exact security exception which you might have caught

Answer 4

Hi,

This error  usually appears when a sharePoint page is left idle for a long time. From the exception, i feel that the session is being expired after sometime. Can you try incresing the session time out to see if that helps.

Thanks for the help. Issue is fixed. Actually the issue is the code is doing web.allowunsafeupdate=false. which copy pasted from some other app. 

Basically its copy paste issue.
