Invalid URI: There is an invalid sequence in the string

Hi,

I'm getting a .net yellow page when I'm doing a redirect to a page with åäö in the URL. It's a simple search form where users enter a search phrase into a text box. When the user submits the form I create a URL to the search listing page. The contents in the form is URLEncoded before redirecting.

But on the search result-page I get a .net-error:

"Invalid URI: There is an invalid sequence in the string.
Exception Details: System.UriFormatException: Invalid URI: There is an invalid sequence in the string."

The URL looks something like this:

"http:///Sokresultat/?ph=S%c3%b6k+Person&searchtype=person"

The phrase searched is "Sök Person", but all texts with åäö cause the same problem.

I'm running EPiServer 5.1.422.256. Any ideas what might cause the problem?

Regards,

Peter

I forgot to mention that the site is an internal intranet site where users are always logged on (through integrated authentication).

Hi,

This is registered bug which has been fixed in SP3
Bug #10555: Querystring with åäö crashes page if friendlyurl is enabled

Possible Workaround:
Do you have a file named: EPiServerLog.config in your site root? If you have, and that file contains a root logger on <level value="debug" />, change that to <level value="error" /> your page will not crash anymore.

Thank you!! Logging error messages only solved it.

I thought I was going crazy because I've seen the error appear and disappear w/o any real explanation =)
