Non english letters in request url:s is replaced with question mark

Reply Contact

I don't know if this is a ASP.NET or IIS issue, but maybe someone can point me in the right direction.

I have an asp.net Framework 2.0 application that is moved from an IIS 5.0 environment to IIS 7.0, Server 2008. When running the app in Integrated pipeline mode all request url:s with non english letters, like the swedish letters å, ä, ö is replaced with a question mark (?) in the query string. If i switch to run the app in Classic mode everything works fine. If the request url is url encoded it works too, but we have a lot of users that are used to create links without the need to url encode them. And it doesn't matter what encoding the site is using, it is using ISO-8859-1 as both request and response encoding, I have tried switching to utf-8 without any improvement. Does anyone have any idea?

Hi Benjamin,

Interesting to say the least. Is there anything in the event log? What locale is your system configured to process Unicode charactors.

Control Panel > Regional and Language Settings > Administrative tab.

I have forwarded the thread to asp.net developers - meanwhile, if you can cook up a small repro (with url and server-side code which uses/displays it) - that would probably speed up the investigation.

Benjamin,

Unfortunately, you've found a bug. We will be fixing this in the next service pack. In the meantime you can work around the problem by running in classic mode, using HttpRequest.RawUrl to access the query string, or by URL encoding characters above 0x7F. I apologize for the inconvenience. Thank you for reporting this issue.

Thank you for the answer, i'll stick to classic mode until the next service pack. Is there an estimated time of arrival for the service pack?

I think the next service pack will be available this summer, but I don't have an exact date. The fix is already queued up for the next service pack, and will definitely be part of it.

Thanks,
Thomas

The IIS7 application pool can be configured to run in what's called Classic Mode. This allows ASP.NET to run in a mode that is compatible with IIS6. By default, the application pool is in what's called integrated mode. See Application Pool properties in IIS Manager.
