Sitefinity A potentially dangerous Request.Path value was detected from the client (?)

问题

I am using Sitefinity 5.1 and RadGrid in this example.

I have been troubleshooting one of our pages on development server this morning and I have confirmed that it behaves differently on the page with the styling (template) than on the barebones page (no styling, no scripts etc):

1. The page does not work in Chrome but does work in IE and Firefox
2. The page on a bare-bones page (no template, header, or anything else) works in IE, Firefox and Chrome

Code used:

Response.Redirect(String.Format("~/services/separation-by-code/managesbyc?id={0}", DateTime.Now.Ticks.ToString()));

I am using ticks to refresh the page before I get there.

Here are some results:

Firefox: seabass.ptagis.org/services/separation-by-code/managesbyc?id=634854696522350585 -> works

Chrome on the bare-bones Sitefinity page: seabass.ptagis.org/services/separation-by-code/managesbyc?id=634854701574768045 -> works

Chrome on the styled page (CSS, Scritps, etc): seabass.ptagis.org/services/%2fservices%2fseparation-by-code%2fmanagesbyc%3fid%3d634854699444302751 -> nope

I get the server error attached below.

I did go through all the steps of setting web.config httprequests = 2.0 and page validations = false. That did not help.

Any help is appreciated.

If you're using .NET 4.0, you should be able to allow the url containing a question-mark (?) via the web.config

<system.web>
   <httpRuntime requestPathInvalidCharacters="&lt;,&gt;,*,%,&amp;,:,\" />
</system.web>

Note, I've just removed the question-mark (?), the original default string is:

<httpRuntime requestPathInvalidCharacters="&lt;,&gt;,*,%,&amp;,:,\,?" />
