Url with special char #

Question

I've to show with a browser some files that contains this # on the name. Using it on the url the file seems to be not available.

How can I configure IIS or my web.config to allow this?

thanks, Andrea

@Mr47 - this question is a duplicate, but because of the `#` it's hard to find. — ChrisF, May 17 '11 at 14:28

That's not how URLs work.

The # character is used to denote the hash portion; anything after it is not sent to the server.

You need to escape the # as %23

Use the URLEncode method to encode the filename for the querystring

As mentioned, the # character is a special character to denote a bookmark on a page

You need to UrlEncode the file name as you build your URL. This will escape the '#' character, allowing the browser to interpret it appropriately.

Proper encoding is very important for preventing Cross-Site Scripting attacks against your application, which can be devastating.
