Session Object & Link Navigation

Alex Maghen

5/22/2007 10:51:00 PM

I'm building an ASP.NET Mobile Web application that uses Session. Because I
am also doing FormsAuthentication, I've set up my Web.Config with certain
settings I read I should use. It looks like:

<system.web>
<compilation debug="true"/>
<authentication mode="Forms">
<forms loginUrl="~/Login/Default.aspx"
name="HomoMoAuth" timeout="10" path="/">
</forms>

</authentication>
<authorization>
<allow users="*"/>
</authorization>

<sessionState
mode="InProc" cookieless="true" timeout="20"
/>

<httpRuntime useFullyQualifiedRedirectUrl="true" />

<mobileControls
cookielessDataDictionaryType="System.Web.Mobile.CookielessData" />

</system.web>


ANYWAY, here's my problem: It seems that, maybe, because of the
"useFullyQualifiedRedirectUrl" or something, I can't really use the "~" in my
Link Paths. If I do, I loose my Session object. Can someone help me
understand how/if I can still use the "~"? I like it!

Hi Alex,

It's related to the cookieless session:

<quote>
#ASP.NET Web Site Paths
http://msdn2.microsoft.com/en-us/library/ms1...
Note

For mobile pages only, if your application relies on cookieless sessions or
might receive requests from mobile devices that require cookieless
sessions, using a tilde ("~") in a path can result in inadvertently
creating a new session and potentially losing session data. To set a
property on a mobile control with a path that includes a tilde (such as
"~/path"), resolve the path using the ResolveUrl method before assigning it
to the property.
</quote>

Hope this helps.

Walter -

Thanks for this. It *does* seem to improve things somewhat. Now I have
another related question: Let's say I want to create my own Link control
which will automatically perform this ResolveUrl() function and also will do
some other things to alter the standard <mobile:link> control. If my new
control is defined as

public partial class AxMobileLink : System.Web.UI.MobileControls.Link

Is there a way that I can sort of automatically support all of the
properties and methods exposed by the constituent <mobile:Link? without
writing my own proerty and function overriding each one which does nothing
but call the base?

Walter -

I am now confused a little further. Let's say I want to place two links on a
Mobile form with the Web.config settings I defined below. The links are as
follows:

1. ~/Default.aspx
2. SomeFolder/Default.aspx

You recommended that I user ResolveURL() on these paths before placing them
in the NavigateURL field of the <mobile:Link> control. The problem is, if I
do that for #1 above, it works fine. But if I do it for #2, it doesn't behave
properly. How am I supposed to know when to use ResolveURL and when now?

Hi Alex,

Please try following approach:

public class Class1 : Link
{
protected override void OnPreRender(EventArgs e)
{
NavigateUrl = Page.ResolveUrl(NavigateUrl);
base.OnPreRender(e);
}
}


Using this customized Link control will make sure it calls ResolveUrl
before displaying the hyperlink.

Let me know if this works for you.
