Hi,
the & (ampersand) is a reserved character and is not allowed as part of the path of an url. Ampersands are used to separate url parameters, so you will have to use another character like underscore or dash.

the problem is our old site used ampersand on about 20 urls and google have indexed them trying to redirect thrm to the new page that does not have them

But if you need the url this way you would have to escape the ampersand with &amp; in the config.

Hi,
could you perhaps explain where and how you redirect (custom coded, ...)?
At least the last posted app key is valid in regards to general web.config rules.
Do you have a screenshot/detailed error message?
Thanks.

Ah,
here we go
http://stackoverflow.com/questions/6025522/getting-a-potentially-dangerous-request-path-value-was-detected-from-the-client
You will have to configure the following setting in web.config (thats the default value)
<httpRuntime requestPathInvalidCharacters="&lt;,&gt;,*,%,&amp;,:,\,?" />
Just remove the &amp; (and any other character you may have) and it should work.
