Then you should also know that this error is persisting because the values given above might be an XSS attack. If you are sure that you want to accept this type of values on your dabatase you may explicitly remove this validation by adding this tag to your page’s masterpage or 1st line of tag.
If you are on ASP .NET MVC you can add this to your model, assuming that your model has the content variable.
[AllowHtml] public string content = String.Empty;
Thanks hope it help you allot. Also if you are not familiar with XSS attacks, I will try to make an article for that so you can create your own script that is hack-able, be able to prevent it, and know what are it’s crons.
The said code will give you the full url path to which your user came from.
Example is http://google.com/?some-strings=goes-here
So you can check if its from a user from a google with a particular search string.
Just a Note. It can also received the same domain to which your site is in. For an instance your domain is http://domain.com then you referesh the page, the said code will return http://domain.com because you just refresh the page.
