FIX: A POST request to a webpage that should redirect responses to a different webpage does not redirect responses in IIS 7.0 or in IIS 7.5

View products that this article applies to.

Symptoms

Consider the following scenario:
  • In Microsoft Internet Information Services (IIS) 7.0 or in IIS 7.5, you have a webpage in an application that accepts a POST request and then redirects to a different webpage.
  • You enable output caching on the application, and the cache is built up after you send GET requests to the webpage together with parameters.
  • A POST request is sent to the webpage.

In this scenario, the webpage is not redirected as expected.

For example, you build a default.aspx webpage that contains a button. The webpage contains the following code under the Button click event.
protected void Button1_Click(object sender, EventArgs e)
{
Response.Redirect("./hello.aspx", false);
}

When a request accesses the default.aspx webpage and then the button is clicked, a POST request is submitted. HTTP code 302 is logged, and the webpage is redirected successfully to the hello.aspx webpage.

In this example, the IIS log contains an entry that resembles the following for the POST request:
#Fields: datetime s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken


datetime ::1 POST /folder_name/default.aspx id=1 80 - ::1 Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 302 0 0 6

However, if lots of GET requests access the default.aspx?id=1 webpage and the IIS cache is built up, you are not redirected to the hello.aspx webpage when you click the button on the default.aspx webpage. Instead, an HTTP code 200 is logged in the IIS log. The STTP code 200 resembles the following:
#Fields: datetime s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken

datetime ::1 POST /folder_name/default.aspx id=1 80 - ::1 Mozilla/5.0+(compatible;+MSIE+9.0;+Windows+NT+6.1;+WOW64;+Trident/5.0) 200 0 0 6

Cause

This problem occurs because the POST request is served incorrectly from the IIS cache that is built up by the GET requests.

Prerequisites

You must have IIS 7.0 or IIS 7.5 installed on one of the following operating systems to apply this hotfix:
  • Windows 7
  • Windows 7 Service Pack 1 (SP1)
  • Windows Server 2008 R2
  • Windows Server 2008 R2 Service Pack 1 (SP1)
  • Windows Vista Service Pack 2 (SP2)
  • Windows Server 2008 Service Pack 2 (SP2)

Restart information

You must restart the computer if IIS is running when you apply this update.

Replacement information

This hotfix does not replace a previously released hotfix.

File information

The English version of this hotfix has the file attributes (or later file attributes) that are listed in the following table. The dates and times for these files are listed in Coordinated Universal Time (UTC). When you view the file information, it is converted to local time. To find the difference between UTC and local time, use the Time Zone tab in the Date and Time item in Control Panel.

Windows Vista and Windows Server 2008 file information notes
Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
    VersionProductMilestoneService branch
    6.0.6000.16xxxWindows VistaRTMGDR
    6.0.6000.20xxxWindows VistaRTMLDR
    6.0.6001.18xxxWindows Vista SP1 and Windows Server 2008 SP1SP1GDR
    6.0.6001.22xxxWindows Vista SP1 and Windows Server 2008 SP1SP1LDR
    6.0.6002.18xxxWindows Vista SP2 and Windows Server 2008 SP2SP2GDR
    6.0.6002.22xxxWindows Vista SP2 and Windows Server 2008 SP2SP2LDR
  • Service Pack 1 is integrated into the original release version of Windows Server 2008. Therefore, RTM milestone files apply only to Windows Vista. RTM milestone files have a 6.0.0000.xxxxxx version number.
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information for Windows Server 2008 and for Windows Vista" section. MUM and MANIFEST files, and the associated security catalog (.cat) files, are critical to maintaining the state of the updated component. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
