Hello,

I'm new to umbraco, and have stumbled across exaclty the same issue. I posted about it here: http://our.umbraco.org/forum/developers/api-questions/12095-Url-Rewriting-tilda-no-longer-finding-site-root

I'm having an additional issue where paths are being resolved incorrectly on the re-written pages too. But I assume when one is fixed the other will be sorted too.

I know it has been a while, but i'm clutching at straws. Did you manage to find a solution to this problem?

Regards

Dean

I'm still looking for a solution to this, too...

In a traditional asp.net app, I'd have an overridden form control (pre 3.5 SP1), such as:

 public class UrlRewriteForm : System.Web.UI.HtmlControls.HtmlForm
    {
        protected override void RenderAttributes(HtmlTextWriter writer)
        {
            writer.WriteAttribute("name", this.Name);base.Attributes.Remove("name");
            writer.WriteAttribute("method", this.Method);
            base.Attributes.Remove("method");
            this.Attributes.Render(writer);
            base.Attributes.Remove("action");
            writer.WriteAttribute("action", HttpUtility.HtmlEncode(Context.Request.RawUrl));
            writer.WriteAttribute("onsubmit", "if (typeof(WebForm_OnSubmit) == 'function') return WebForm_OnSubmit();");
            base.Attributes.Remove("onsubmit");
            if (base.ID != null)
                writer.WriteAttribute("id", base.ClientID);
        }
    }

or with > 3.5 SP1, as simple as

Form1.Action = Context.Request.RawUrl

But that seems to be overridden somewhere in Umbraco 4.6... Is there something obvious I'm missing?

Many thanks,

Kev.

Actually, I've just found a solution to this, to remove the action tag altogether - then nothing seems to be changed further down the lifecycle... Obviously this will only be workable if you only ever have pages that postback to themselves

 public class UrlRewriteForm : System.Web.UI.HtmlControls.HtmlForm
    {
        protected override void RenderAttributes(HtmlTextWriter writer)
        {
            writer.WriteAttribute("name", this.Name);base.Attributes.Remove("name");
            writer.WriteAttribute("method", this.Method);
            base.Attributes.Remove("method");
            this.Attributes.Render(writer);
            base.Attributes.Remove("action");
            writer.WriteAttribute("onsubmit", "if (typeof(WebForm_OnSubmit) == 'function') return WebForm_OnSubmit();");
            base.Attributes.Remove("onsubmit");
            if (base.ID != null)
                writer.WriteAttribute("id", base.ClientID);
        }
    }

In the web.config

<controls>
<add tagPrefix="prefix" namespace="<namespace>" assembly="<assembly>"/>
...
</controls>

<prefix:UrlRewriteForm runat="server" ID="Form1">
...
</prefix:UrlRewriteForm>

Now my URLs stay rewritten.  Happy days :)

Thanks, that worked.

I read somewhere that it is dodgy to remove the action attribute as the behaviour is unspecified in the html spec so some browsers might break if you leave it blank, so I made it work like first example where it uses the RawUrl. I also changed it a little for .NET 4 so it wouldn't mess with any other stuff that the .NET form control does (the RenderAttributes function does quite a lot if you look at it in reflector):

    public class UrlRewriteForm : System.Web.UI.HtmlControls.HtmlForm
    {
        protected override void RenderAttributes(HtmlTextWriter writer)
        {
            // Render attributes normally to a string
            StringBuilder sb = new StringBuilder();
            StringWriter tw = new StringWriter(sb);
            HtmlTextWriter hw = new HtmlTextWriter(tw);
            base.RenderAttributes(hw);
            string s = sb.ToString();

            // Replace action with custom action
            string newAction = "action=\"" + HttpUtility.HtmlEncode(Context.Request.RawUrl) + "\"";
            s = System.Text.RegularExpressions.Regex.Replace(s, "action=\".*?\"", newAction);

            // Write the new attributes
            writer.Write(s);
        }
    }

It's not particularly great, but it works OK for me :-)

is working on a reply...
