Silverlight - CGI And Debugger - Can't Pass Through URL Because Actual Request Is Coming From Server
Oct 4, 2010
I've got a Silverlight app that has to accept some initial data when it fires up. That data, unfortunately, MUST come from XML input. In addition, I can't just pass it through the URL because the actual request is coming from a server external to my own.
So the basic setup is this: Remote server needs to launch my app. Remote server pops open a window on the user's PC with a URL directed at a CGI application that can accept the XML input. The CGI app parses the input and spits out an HTML page containing the Silverlight app with all of the init params set. Long story short: When the Silverlight app is opened this way I can't debug it. I attach to the process, but none of the break points can be hit.
I tried every way in the world to get the ASP.NET page that would normally host the Silverlight app to accept the XML in the URL but it would get stripped by ASP.NET because of security reasons and no amount of modifying the config file would fix it (since it was stemming from the other web server presumably).
I want to find URL from the incoming request is coming. I am giving the explanation below
Suppose a client is redriecting the request from www.xyz.com to www.abc.com/ClientInfo.aspx. Now www.abc.com is in the asp.net c#. Now i want to find www.xyz.com on www.abc.com/ClientInfo.aspx page.
I want to embed a silverlight app into a web page and have the height/width of the div that contains the silverlight control match the dimensions of the actual size of the silverlight control.
I essentially want the div to stretch to accommodate the size of the silverlight control. I do not know what size the silverlight control will be before it loads as it is pulling in data and adding controls dynamically. I want to avoid dueling scroll bars and use only the browser scroll bars.
I need this to work in both IE and Firefox.Is there a way to accomplish this?
When a create a web project ( ex webapplication) and when we publish it. We have Two folders created ( App_data and Bin) and have one file Default.aspx and web.config file.
My question.
1. Where is Default.aspx.cs file?
2. When a request will comes for example ( http://Mywebsite/default.aspx)
Does it goes to default.aspx page? or it goes to the webapplication.dll file which is under bin folder?
for SEO purposes, instead of refreshing the page every click of a product, is it possible to click on the product and when the server comes back with the response, to change the URL of the page to reflect the new link to information currently on page?
point is to have ajax redraw the product details portion of the page but have SEO friendly url's displayed so if people want to bookmark the currently selected product, it will bookmark the right url instead of the generic one to access the products page..
For example... here's my entry point:
Products.aspx
product1product2product3 If I were to click product1, the request goes to the server with roducts.aspx?id=product1 but the url is still products.aspx on the response meaning that when people bookmark the product1 item, and they send the link to a friend, the friend always gets the generic product.aspx page.
I'm trying to get around this without refreshing the full page (postback).
My web site is integrated into a client web site. Client web site reaches out to my site through an Xml request and I return Html embedded in an Xml response. Client site then displays the Html in an area on a page on their site. All is well so far...
Now, there is a link on the Html that does an HttpPost back to my site which causes a re-direct to another page on my site. i.e. [URL] -> HttpPost -> [URL]-> Response.Redirect("CookieTest.aspx"). Still, all is well. [URL]
All of the above can occur without authentication to mysite. Where I start running into problems is when CookieTest wants to do a FormsAuthentication.SetAuthCookie(). If I put a button on CookieTest that does FormsAuthentication.SetAuthCookie() and then Response.Redirect("SecurePage.aspx"), still under [URL], the SecurePage does not recognize the authentication because the auth cookie is not present.
1. Navigate straight to CookieTest.aspx
So I simplfied the problem into basic cookie set/read excercise and used the code below to test out cookie writing/reading ability. When I call the page directly from the browser I see that on initial load the response cookies are empty. Then on button click I see that the cookie is properly set in the response. Then on subsequent page refresh I see that the page load shows the request cookie.
2. Navigate to CookieTest.aspx in an HttpPost from [URL], as mentioned above.
Now on button click I see the cookie in the Response but do not see it come back in the Request of subsequent page refreshes, as if the client browser is rejecting cookies set by my server.
3. Navigate straight to CookieTest.aspx, then do the HttpPost from [URL]
In this case, since the cookie was set during a straight navigation to CookieTest.aspx, the cookie is present in the subsequent HttpPost/Redirect from [URL]. CookieTest.aspx has full access to the cookie and can even delete it.
4. Have CookieTest.aspx pop a new browser window simply sets the cookie and closes itself down.
Similar to #3, if the cookie is set through a popup window and then CookieTest is refreshed the cookie is present in the Request.
Notes:
The code does prove that the client browser accepts cookies.
When my page (CookieTest.aspx) is shown within the frame on the [URl] page, during any link back to my server, the Request.Url.Host shows my domain.
First, we are constrained to using an existing web framework that handles authentication and authorization. The web project uses forms authentication and writes to an encrypted cookie. The user information is exposed to the aspx pages as a property:
LoggedInUser.Current
This has several properties including the userId and role list.
I've looked at using initParams, but haven't been very successful there (edit: I couldn't do it dynamically originally). I've created a simple POCO entity with a [Key] attribute, but I need to at least be able to pass the userId from the aspx page to the imbedded silverlight.
What is the easiest way to pass a dynamic object from aspx to silverlight 4?
[Code]....
Then used Slugster's example to use the values on the Silverlight side.
Warning: Passing user information via init params exposes the info as plain text to the user viewing the page (they just have to view the source). We ended up using an authentication domain service and using the same user object as the aspx
WebApp1: on IIS and configured with Windows authentication. Get User account from AD.
WebAPP2: a java web app on another windows box in same domain with authentication from AD
On web app1, I have a http handler like
public class MyHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { string url = "http://WebApp2/Test"; HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(url); CredentialCache myCache = new CredentialCache(); NetworkCredential netCredential = new NetworkCredential("myname", "mypassword", ""); myCache.Add(new Uri(url), "Basic", netCredential); //... myReq.Credentials = myCache; //.... } }
in above way, I can set authentication in code and pass it WebApp2.
But I don't want to put name and password in code. User info already available on WebApp1: in context.User I can find out the user info who already logined into WebApp1, so I want to pass this credential to WebApp2. I have tried to do following:
I have a GridView and I need update some data inserting HTML CODE; I would need this data been stored encoded and decoded on request.
I cannot in any way disable globally "Request Validation" and not even at Page Level, so I would need a solution to disable "Request Validation" at Control Level.
At the moment I am using a script which should Html.Encode every value being update, butt seems that "Request Validation" start its job before event RowUpdating, so I get the Error "Page A potentially dangerous Request.Form ... ".
I have this select statement which joins two tables and produces one column as its result. What I'm figuring out is how to add this data into another table as a new column. The output of the select statement and the table I'm going to transfer the data to has the same number of rows. Should I put it first in a temporary table? This column shouldn't allow nulls also.
While using Ajax in web applications we use XML to transfer the data between server and client. However XSS validation comes into picture, So questions are,1. Is passing XML like this is correct?2. Are we exposed to security issues if we turn off XSS validation?3. Can passing Ajax request with header (content-type = application/xml) solve this problem ?JSON is also good approach to transfer the data but that to invoke XSS.
I had a .net 4.0 vb.net page that was setting session variable and setting a hidden form value to the same value. It was a paypal buy now button. When the user selects it, they are sent to paypal for payment. If the transaction is good, they are redirected back to another page on my site and a hidden value is sent back with the invoice I originally sent them. They are sending the form value, but my session variable does not available.
From the user point of view it's all seamless.. Is it the same session? And should my session variable be available?
Here is an easy one:I need a stable simple file uploader with a progress bar, I have found lots of fancy ones from the search. However, I need the community opinion on which ones to go with? Tutorial links would be appreciated.BOUNTY: I have a FileStream which I would like to upload to a server, below is a sample server server URL:string uploadUri;string SavedFileName = "testXRay.jpg" uploadUri = @"http://localhost/MyApplication/Upload/Images/" + SavedFileName;I am adding a bounty in hope to get a working solution which I could use from my SL application. MyApplication is hosted in IIS.
I have a Silverlight 3 application. It accesses WCF services that run on IIS. If I let the application sit for a while with no activity, it appears that I lose my connection to the server/login authentication, and my service calls fail.
It would appear that I am being logged out for security purposes, but this is not an area that I understand well. We are using a federated STS to create an encrypted token for security.
Can someone explain what is happening (if my description is clear enought), and how can I detect this event in my Silverlight application and redirect them back to the login page.
i have develop my silver light application using asp.net and i want to deploy it , i am using vs 2010 and planing to use vsweb deployment project 2010 for beta
I am working on an Entertainment Website, my client wants to save videos in the database, i am a bit aware of silverlight, that it can be done through microsoft's silverlight platform.
how to accomplish my goal, i am using ASP.Net with C# and LINQ and backend in MS-SQL Server 2008.
I have an ASP.NET site running on the Visual Studio Development Server. I also have a silverlight project in my solution. I get the error:
Error: Unhandled Error in Silverlight Application Code: 2104 Category: InitializeError Message: Could not download the Silverlight application. Check web server settings
After some research, it seems I need to do the equivalent of setting the MIME type in HTTP Headers in IIS for VSDS. Is this right?
If so, how do I do this? If not how do I get my silverlight to run in my ASP.NET solution using Visual Studio Development Server?
