  1. POWhat's wrong with my url encoding?
    text
    copied!<p>In my asp.net mvc application I created the following link:</p> <pre><code>http://localhost:2689/en/Formula.mvc/351702++LYS+GRONN+5G+9%252f2++fds </code></pre> <p>I get error 400 (bad request).</p> <p>I think it blocks at the %25 (forward slash).<br> What am I doing wrong?</p> <p><strong>--EDIT 3--</strong><br> I tried not encoding anything at all but rather rely on the default encoding of Url.RouteUrl().<br> It seems that this doesn't encode the "/" for some reason.<br> If I encode it myself first, I end up with the doubel encoded %252f. This gives me a bad request for some reason.. Why?!</p> <p><strong>--EDIT 2--</strong><br> I generated the last part of the URI as follows: </p> <ol> <li>Take the id.toString</li> <li>Take the HttpUtility.UrlEncode(name)</li> <li>Take the HttpUtility.UrlEncode(code)</li> <li>String.Format("{0}--{1}--{2}") with the values from the previous parts</li> <li>Add it as a parameter to Url.RouteUrl()</li> </ol> <p>After that my action gets this parameter again, splits it at -- and HttpUtility.Decode() the values back.</p> <p>I do it this way because the two last parameters are optional, but functional parameters. IF they are defined in a previous step, they have to be carried along to the other pages.<br> Less abstract: A color can have multiple names, but if a user selected it by a particular name, it should be kept throughout all the other pages.</p> <p><strong>--EDIT 1--</strong><br> It also looks like HttpUtility.UrlEncode() and Url.Encode() return different results :S </p> <p>If I don't encode the "/", it acts as a separator=>no luck there. If I encode it with Url.Encode() I end up with %2F => Code 400 If I encode it with HttpUtility.UrlEncode() I end up with %25 => code 400</p> <p>Because 400 doesn't even let it through to asp.net-mvc, the route debugger is of no use :(</p>
