MVC :: Request.Params Request.Form Not Working In Internet Explorer 8?

Jun 29, 2010

This is a input

<input type="image" src="<%=Url.Content("~/images/shopping-cart.jpg")%>" alt="shopping cart" id="btnshoppingCart" name="btnshoppingCart" value="shoppingCart" />

when i browse the page with firefox and click on the input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is statisfied.

When i browse the same page with internet explorer 8 and click on the same input Request.Params["btnshoppingCart"] != null or Request.Form["btnshoppingCart"] != null is not satisfied. When i used the watch i saw that there is no key by the name of "btnshoppingCart" in either Request.Form or Request.Params if input is clicked from internet explorer. However when it is clicked from firefox there is value "shoppingCart" inside Request.Form and Request.Params against "btnshoppingCart" key. One more strange thing that i observed was that are two keys "btnshoppingCart.x" and "btnshoppingCart.y" inside both Request.Form and Request.Params whenver clicking is done from both internet explorer and firefox. This is happening against all inputs of type image irrespective if the input is present inside a html form or not. Forms are created like this

<% using (Html.BeginForm("Action", "Controller", FormMethod.Post)){%>

The version of internet explorer is 8.0 and firefox is 3.6.6

MVC :: Internet Explorer Always Firing Off A Default GET Request?

Nov 25, 2010

I'm developing a pretty standard MVC application.. I've set the routing up as follows:

[Code]....

Everything works perfectly in all browsers - apart from IE. If I am on, say, Stock/Index/, it will fire the Stock/Index/ GET request, then fire the Stock/NewLines/ request afterwards..Obviously this isn't desired behaivour - as I understand it, the default route value is for when the router can't find the requested controller/action/route, and so sends the request there..Can't seem to find any info on the web about this,

Security :: Authenticate Users By Request.UrlReferrer?

Sep 25, 2010

I am working on an app where users are only allowed access if they click through from certain URLs. I.e. I need to authenticate by using the referral url and I am using
Request.UrlReferrer to achieve this.

I am guessing that the Request.UrlReferrer can be tampered with by malicious users to gain access...

HTTP Post Doesn't Work On Internet Explorer 8 (after Redirection)

Feb 4, 2011

I'm trying to redirect a domain to another site, without changing the first URL (users should keep viewing http://www.myurl.org since the new URL would be https://wwws.enterprisedomain.com).

I could do this, inserting a frame in the index.htm of the first domain (I know it's not the best practice, but it worked well for now):

<frame name="main" src="https://wwws.enterprisedomain.com">

The fact is that https://wwws.enterprisedomain.com has a login mechanism in ASP.NET. It's OK on Firefox and Chrome, but when we use Internet Explorer 8, it seems that POST doesn't work!

Security :: Internet Explorer 8 Denies Session Cookies

Jul 22, 2010

i am having this weird problem only when i deploy my site [localy Everything works fine] when you try loging in from IE 8, the page simple refreshes! and no authentication takes place After lot of research, i found out that Internet Explorer 8 denies session cookies and to confirm this, i unchecked Enable protected mode (can be found in, internet options, security), and then tried logging in, it worked perfectly fine just like it did in other browsers [Firefox and google chrome]. I have found one solution which is to lower the security level, but i cant tell every visitor on my site to do that since its not practical.

C# - Use Request.UrlReferrer When Determining Referrals?

Sep 9, 2010

I came upon an interesting discussion with my team around the use of HttpRequest.UrlReferrer and wanted to solicit feedback from the community. According to the W3C spec:

The Referer[sic] request-header field allows the client to specify, for the server's benefit, the address (URI) of the resource from which the Request-URI was obtained (the"referrer", although the header field is misspelled.) The Referer request-header allows a server to generate lists of back-links to resources for interest, logging, optimized caching, etc. It also allows obsolete or mistyped links to be traced for maintenance. The Referer field MUST NOT be sent if the Request-URI was obtained from a source that does not have its own URI, such as input from the user keyboard.as input from the user keyboard.

The Request.UrlReferrer object does the work of converting referral strings that contain well formed URIs to an object with properties on every request. According to our logs there are requests that come in that contain invalid data in the referral such as:

localhost
app:/BeamBackTest.swf
app:/multtiple.swf
app:/AFriendFeed.swf
ALToolBar
app:/index.html
mhtml:file://C:Documents+and+SettingsUserDesktoporacleWhat+is+a+View+in+Oracle+-+Stack+Overflow.mht

Using Request.UrlReferrer would mean the above cases would be NULL. Is it better to discard the invalid data based on the W3C spec by using Request.UrlReferrer or preserve it by using Request.ServerVariables["HTTP_REFERER"] even though the data may be interesting, but potentially useless.

Configuration :: Migrating The Request.UrlReferrer.ToString() To The Web.config File

Jan 10, 2011

I have the following code in 'main.cs' file where I am checking for a condition

protected void Page_Load(object sender, EventArgs e)
{
if (Request.Form.Get("task") != null && Request.Form.Get("postToURL") != null &&
Request.UrlReferrer.ToString().Substring(0, 31).Equals("http://cs.astra.co.in:4040"))
{
ASCIIEncoding encoding = new ASCIIEncoding();
<SO ON>

Instead of checking for the URL [URL] in 'main.cs', Can I check for the same condition in the 'web.config' file ? If so, How can I do that ?? Is there any way to transfer the part -- Request.UrlReferrer.ToString().Substring(0, 31).Equals[URL] -- into the 'web.config' !!

[Code]....

Iframe Cookie With Internet Explorer?

Aug 23, 2010

I am developing an ASP.NET 4.0 web application in which I am trying to use an iframe to load a third party website:

<iframe id="ifr1" src="http://newdomain.com?id=test&password=123"
width="100%" height="600px">
</iframe>

The newdomain.com is trying to place cookies in the browser and IE dosent like that. I have no control over the application hosted on the newdomain.com. I have read a lot of articles which talk about having a P3P information added to the header of the page which hosts the iframe. So in my application's Global.asax I have the following code:

protected void Application_BeginRequest(object sender, EventArgs e)
{
HttpContext.Current.Response.AddHeader("p3p", "CP="IDC DSP COR ADM DEVi TAIi PSA PSD IVAi IVDi CONi HIS OUR IND CNT"");
}

But this doesn't work and I am really confused now.
