I have a website that has a plus sign in the filename and UWS isn't recognizing those pages. It's treating the '+' as a space. Any ideas how to resolve?

Hi there!

is file name in question looking like "some+page.htm"? Could you please confirm that this behavior is UWS-specific and does not manifest when running the app in IIS?

Thank you,

Actually I found it's an issue with any file that has a special character, not just those with the plus sign. Examples: some+page.htm some&page.htm. It worked in Cassini 2.0 and IIS by adding requestFiltering allowDoubleEscaping=true to the web.config.

Thank you much for bringing this to our attention. We'll test this scenario, but it probably will take next release of UWS to have this problem fixed.

First thing to note is that requestFiltering setting is in the IIS7-specific section of the web.config. It can't affect IIS6, Cassini or UWS. We'll take a look at whether we can support serving files with special chars at all times.

We will keep you posted regarding the progress.

Best wishes,
UltiDev Team.

Hi there!

It turns out standard UrlDecode() does not distinguish between '+' in the query string between '+' in the URL itself, and coverts both using query string rule instead of using exception. We implemented a work-around that will be available in build 18 of UWS.

What about other special characters? From #3 above "Actually I found it's an issue with any file that has a special character, not just those with the plus sign."

Hi there!

Since it's impossible to create physical file with names containing '%', '&', ':' and other special characters, could you please check whether virtual paths, like HttpModules, don't work properly with pre-release build 18?

I am able to create physical files with the following special characters: !@#$%^&(). Only: \/:*?"<>| are restricted in Windows. I will look into your suggestion as well as using IISExpress to resolve. Thank you for your assistance

Hi!

We are sorry, it turns out Visual Studio and not OS refuses to create such items. We will test more special chars and will let you know.

Thank you again,
UltiDev Team.

We tested characters you've mentioned, and all of them, except % and #, which are special URL characters, work fine. '%' in the file name prevents browsers from even sending a request. '#' chops URL as everything following '#' is an internal page bookmark.
