C# - Is Possible To Share HttpRuntime.Cache Between Multiple Web Servers

Nov 10, 2010

We have a web application that is storiing all site data in HttpRuntime.Cache. We now need to deploy the application across 2 load balanced web servers. This being the case, each web server will have its own cache, which is not ideal because if a user requests data from webserver1 it will be cached, but there next request might go to webserver2, and the data that their previous request cached won't be available. Is it possible to use a shared-cache provider to share the HttpRuntime.Cache between the two web servers or to replecate the cache between them, so that the same cache will be available on both web servers?

C# - Amazon EC2 Multiple Servers Share Session State

Mar 12, 2010

I have a bunch of EC2 servers that are load balanced. Some of the servers are not sharing session, and users keep getting logged in and out. How can I make all the server share the one session, possibly even using a partitionresolver solution

public class PartitionResolver : System.Web.IPartitionResolver
{
private String[] partitions;
public void Initialize()
{
// create the partition connection string table
// web1, web2
partitions = new String[] { "192.168.1.1" };
}

public String ResolvePartition(Object key)
{
String oHost = System.Web.HttpContext.Current.Request.Url.Host.ToLower().Trim();
if (oHost.StartsWith("10.0.0") || oHost.Equals("localhost"))
return "tcpip=127.0.0.1:42424";
String sid = (String)key;
// hash the incoming session ID into
// one of the available partitions
Int32 partitionID = Math.Abs(sid.GetHashCode()) % partitions.Length;
return ("tcpip=" + partitions[partitionID] + ":42424");
}
}

Setup Identical <machinekey /> Sections On Each Servers .config File?

Mar 2, 2010

We have a scenario using asp.net Forms Authentication in a web farm and need to setup identical <machinekey /> sections on each servers .config file.

Is it better to store the <machinekey /> section in machine.config rather then web.config? what's the advantages and disadvantages of each approach concerning security?

<machineKey validationKey="[keyhere]"
decryptionKey="[keyhere]" validation="SHA1" />

If its not secure enough, is there any way to encrypt <machinekey /> section like we encrypt our connectionsstring (with DPAPI)? (http://msdn.microsoft.com/en-us/library/ms998280.aspx)

Double Hop On Workgroup Servers Vs Domain Servers

Nov 16, 2010

I am trying to set up my web site on a stand alone server using Windows Server 2003 with IIS 6 which will access SQL server database (2008) on windows 2008 R2 server (also not in the domain) I am using form authentication and I have configured a custom identity account in IIS6. The local account is on both servers with same password and I have registered the account using aspnet_regiis.exe -ga The application pool in my iis6 has the custom local account set as the identity and my web.config file has the appropriate tags in the system.web element <identity impersonate="true" />

The problem is the local account does not seem to get passed to the sql server. Right now my iis settings are anonymous access (using the local acct vs isr) and no authentication specified under that - I did try Integrated and basic but it prompts for the username and password which I do not want. One article I read stated this: windows authentication does not support delegation (passing credentials from one server to another) and is limited to the one hop rule, only a primary token can be passed to a second server. windows
authentication on iis (all versions) gives the thread a secondary(impersonation) token which can not be used to access any network resouce

File.OpenRead() Accesses File On Share Within Workgroup But Not A Remote Share?

Mar 4, 2011

I have an ASP.NET MVC application that attempts to read a file in using a filestream and File.OpenRead().
When the path to the file is a share on the same workgroup, and I give access to NETWORK SERVICE for the share, this works perfectly as desired.

However, when the path to the share is a UNC path to a remote share within the LAN, with read permissions open for "Everyone", the "File.OpenRead()" method throws an exception saying "Could not find a part of the path".

In my test cases I'm debugging locally with the ASP.NET MVC app being given a UNC path to the computer that it's actually running on. It's a share on my C drive, being "Shared" with permissions to "Everyone" for read access.

Is there something in IIS that needs to be configured? If I try to impersonate, in this context, the impersonation doesn't matter because NETWORK SERVICE was the user trying to access the files when it worked for a share in the same workgroup.

C# - How To Obtain One Way Hash For Given String

Mar 10, 2011

Is there a build in library in .NET that can compute secure one-way hash ? I mean a library that implements SHA-2 cryptographic hash function or something similar.

If is there is no SHA-2 implementation some weaker hash funcion would be sufficient. If there are more options I prefer the most secure one.

provide a use example e.g. provide the code that returns one-way hash for string mySampleString.

C# - Get Full URL With Hash To Use As ReturnUrl?

I have such URL

localhost/Login/LogOn?ReturnUrl=/#&q=my%20search%20word&f=1//447044365|2//4

I need to get hash parameters to navigate in the application after authentication.

I try to catch it like this

<input name="returnUrl" value="<%= ViewContext.HttpContext.Request.Url.PathAndQuery %>" type="hidden" />

But result is

/Login/LogOn?ReturnUrl=/

I tried to take away "/#" in the URL, then I get whole URL. But I need to use this URL as it is.

Postbacks Lose The Hash In The URL?

Oct 7, 2010

On an ASP.NET page with a tabstrip, I'm using the hash code in the URL to keep track of what tab I'm on (using the BBQ jQuery plugin). For example:

http://mysite.com/foo/home#tab=budget

Unfortunately, I've just realized that there are a couple of places on the page where I'm using an old-fashioned ASP.NET postback to do stuff, and when the postback is complete, the hash is gone:

http://mysite.com/foo/home

... so I'm whisked away to a different tab. No good.

This is a webforms site (not MVC) using .NET 4.0. As you can see, though, I am using URL routing.

Is there a way to tell ASP.NET to keep the hash in the URL following a postback?

Security :: MD5 Hash Dropping Zeros?

Apr 23, 2010

I need to pass some info to a 3rd party (for tracking) and they require I provide a checksum value which is an md5 hashed amalgamation of some of the other values. This is my code :

[Code]....

They keep rejecting my checksum. When I have tested for the following value passed in preConvert - 300265215063.79 I get :

My code gives : ED4463C84DE9D21B54C4E62F2D72CE

An online MD5 hash gives : 0ed40463c84de9d21b54c4e62f2d72ce

Which apart from the case, is exactly the same apart from missing 2 zeroes.

Validating Facebook Cookie Using Md5 Hash?

Sep 4, 2010

I am trying to incorporate facebook login in my ASP.NET web app and came across the following article which has a code sample for the same.

[URL]

The following is from the article.

Next, and most importantly, the class validates the cookie. This validation uses MD5 hashing to compare the contents of key appended to the app secret to the signature that comes in with the cookie. If these values match we know the key is valid.we know the key is valid.

Why is Md5 hashing being used for that? Why not SHA or some other algo?

What happens if I don't validate the cookie? Can invalid cookies be sent to the server?

In the article, he throws a new security exception if cookie is invalid? What should the user do in such a case?

Store Hash Password In SQL Server?

May 13, 2010

Is this how hashed password stored in SQL Server should look like? This is function I use to hash password (I found it in some tutorial)

public string EncryptPassword(string password)
{
//we use codepage 1252 because that is what sql server uses
byte[] pwdBytes = Encoding.GetEncoding(1252).GetBytes(password);
byte[] hashBytes = System.Security.Cryptography.MD5.Create().ComputeHash(pwdBytes);
return Encoding.GetEncoding(1252).GetString(hashBytes);
}

EDIT: I tried to use sha-1 and now strings seem to look like as they are suppose to:

public string EncryptPassword(string password)
{
return FormsAuthentication.HashPasswordForStoringInConfigFile(password, "sha1");
}
// example output: 39A43BDB7827112409EFED3473F804E9E01DB4A8

Result from the image above looks like broken string, but this sha-1 looks normal....

C# - Javascript Hash And Equivalent Algorithm?

Jan 31, 2011

Using this code on the javascript side and

Using sha As New SHA256Managed
Using memStream As New MemoryStream(Encoding.ASCII.GetBytes("Hello World!"))
Dim hash() As Byte = sha.ComputeHash(memStream)
Dim res As String = Encoding.Default.GetString(hash)
End Using
End Using

I have been unable to recreate the same hash for the same values with these two bits of code.

The javascript implementation returns: 7f83b1657ff1fc53b92dc18148a1d65dfc2d4b1fa3d677284addd200126d9069

and the vb.net example returns: ƒeñüS-ÁHÖ]ü-KÖw(JÝÒ mi"

What am I missing? I assume it's something to do with the character encoding?

Calling Classic Asp Function That Creates Hash Value

Mar 7, 2010

I've a pre-supplied public function in classic asp that creates a hash value - it is pretty complex and I'd rather not convert it to .net if at all possible (mainly as I don't understand half of what it does!) I'm running it under IIS7 on VWD2008 express. How would you call a function in that asp file? do you have to redirect or as it is #included into the asp.net file, is there an eaiser way? At the moment the complier does not spot the function and says it is not declared.
