Prevent UrlReWrite for a specific page type

Vote:

In the SDK , in the article for Friendly URL mentions that EPiServer CMS Furl rewrites all links in HTML when rendering it to the client. In most case, this is working fine. But I have a situation that I don't want the FURL do anything with my links, specially the src-attribute in the <img>.

Took a look at an article , written by Juwen Jin on the labs.episerver.com (http://labs.episerver.com/en/Blogs/Ruwen/Dates/111218/112064/112154/) and tried to doing that by listen to the event HttpRewritingToInternal

static void module_HttpRewritingToInternal(object sender, UrlRewriteEventArgs e)

        {
            string url = e.UrlContext.InternalUrl.Uri.AbsolutePath.ToLower();
            if (url.EndsWith(".jpg") || url.EndsWith(".gif"))
            {
                //Do nothing with the link

		e.IsModified = true;
                e.Cancel = true;
            }
        }

But it doesn't give any effect. The links still are rewritten and rebased to current pages path.

Also tried with  HtmlRewriteUrl-event in RewritePipe for HtmlRewriteToExternal, but could neither solve the problem.

Anyone has any idéa?

I think you should be using HttpRewritingToExternal if you wan't to modify outgoing links.

Also remember that server controls relocates your paths (link asp:image and img with runat=server).

Actually, i had tried with HttpRewritingToExternal too but the result was the same.

my original link "/images/mypic.gif" was still being converted to "../../images/mypic.gif" (is this what you ment "server controls relocates your paths (link asp:image and img with runat=server)" ?)

If I set default provider for urlRewrite to EPiServerNullUrlRewriteProvider, the link "/images/mypic.gif" is maintained and it's exactly what I want!

Any other ideas?

Here is my code

public class UrlRewriteHandle : System.Web.IHttpModule
    {
        #region IHttpModule Members
        static bool isURLHandlerInitialized = false;
        public void Dispose()
        {

        }
        public void Init(System.Web.HttpApplication context)
        {
            if (!isURLHandlerInitialized)
            {
                try
                {
                    if (EPiServer.Web.FriendlyUrlRewriteProvider.IsFurlEnabled)
                    {
                        UrlRewriteModule.HttpRewriteInit += new EventHandler(UrlRewriteModule_HttpRewriteInit);
                    }
                    isURLHandlerInitialized = true;
                }
                catch
                {
                    isURLHandlerInitialized = false;
                }
            }
        }
        static void UrlRewriteModule_HttpRewriteInit(object sender, UrlRewriteEventArgs e)
        {
            UrlRewriteModuleBase module = sender as UrlRewriteModuleBase;
            if (module != null)
            {
                module.HttpRewritingToInternal += new EventHandler(module_HttpRewritingToInternal);
            }
        }
        static void module_HttpRewritingToInternal(object sender, UrlRewriteEventArgs e)
        {
            string url = e.UrlContext.InternalUrl.Uri.AbsolutePath.ToLower();
            if (url.EndsWith(".jpg") || url.EndsWith(".gif"))
            {
                e.Cancel = true;
            }
        }
        #endregion
    }

Hiue,

Where do you use this link? Do you have runat=server on the component where you set the src attribute? If yes, have you tried using "~/images/mypic.gif"

I have tested with "~/images/mypic.gif", and the link was converted to "../..//images/mypic.gif"
