Introduction. Whenever a browser makes an HTTP request to a web server, it sends along several HTTP headers. These HTTP Headers are used to provide the web server with information. For instance, if the browser supports compression it will send along an Accept Encoding HTTP Header, which lets the web. Any cookies previously set by the web server are sent from the browser back to the server via the Cookies. HTTP Header. The browser also sends the User Agent HTTP Header, which the web server can parse to determine the browser IE, Firefox, Safari, etc., the version. Similarly, the web server includes a number of HTTP Headers when it sends back the contents of the requested resource. These headers are used by the browser to determine how. The web server also sends back identifying information, much like the User Agent request HTTP Header. These identifying headers indicate the web server version along with the ASP. Thats all there is to it Removing the XAspNetMvcVersion HTTP Header The XAspNetMvcVersion HTTP Header is automatically added by the ASP. NET MVC framework. Horse Handicapping Software Ratings.

NET version numbers. This article looks at how to remove these identifying HTTP Headers in both IIS 6 and IIS 7. Read on to learn more Inspecting the Web Servers Response HTTP Headers. In order to examine the HTTP Headers sent from your browser to a web server and those returned from a web server back to the browser, you need to install a program or. Fiddler is a free, stand alone application from Microsoft that logs all HTTP and HTTPS. This logged data includes the response and requests HTTP Headers, among other useful data. For this article I assume the reader is already familiar. Fiddler if this is not the case, take a moment to read Troubleshooting Website Problems by Examining the HTTP. Traffic, which details how to install and use Fiddler. Using Fiddler, visit a website that you know is powered by Microsofts IIS web server and ASP. NET technology, such as Microsofts official. ASP. NET website. By default, such websites will include three identifying HTTP Headers. Server specifies what web server version is being used. Examples of this headervalue pair include. Server Microsoft IIS6. Server Microsoft IIS7. X Powered By indicates that the website is powered by ASP. NET. X Asp. Net Version specifies the version of ASP. NET being used. Note that this value returns the core framework version, meaning that even if. ASP. NET 3. 5 the X Asp. Net Version header will report version 2. Possible values include. X Asp. Net Version 2. X Asp. Net Version 1. X Asp. Net. Mvc Version specifies the version of ASP. NET MVC being used if any. Possible values include. This identifying information is not used by the browser in any way, and can safely be removed. The remainder of this article examines how to remove these HTTP Headers. Removing the X Asp. Net Version HTTP Header. The X Asp. Net Version HTTP Header broadcasts to the world what version of ASP. NET is being used by your web server. Removing this header is a cinch simply add. Web. config file. Runtime enable. Version. Headerfalse. Thats all there is to it Removing the X Asp. Net. Mvc Version HTTP Header. The X Asp. Net. Mvc Version HTTP Header is automatically added by the ASP. NET MVC framework. If you are not using ASP. NET MVC then this header wont be present. However, if you are using ASP. NET MVC and want to remove this header you can do so by setting the Mvc. Handler. classs Disable. Mvc. Response. Header property to. True in the ApplicationStart event handler in Global. CMvc. Handler. Disable. Mvc. Response. Header true VBMvc. Handler. Disable. Mvc. Response. Header True. Removing the X Powered By HTTP Header. The X Powered By HTTP Header is not unique to ASP. NET. Other server side programming technologies, such as PHP, routinely include such an HTTP Header. When ASP. NET is installed it adds X Powered By ASP. NET as a custom header in IIS. Consequently, we need to remove this header from IISs configuration. If your website is hosted in a shared environment and is not using IIS 7 and the integrated pipeline, you may need to contact your web host provider and ask them to. If your website is hosted on IIS 7 and uses the integrated pipeline you can programmatically remove the X Powered By header. HTTP Module. See the Removing the Server HTTP Header section later on in this article for more details. To remove the X Powered By header from IIS 6. Launch the Internet Information Services IIS Manager. Expand the Web Sites folder. Right click on the website to modify and choose Properties from the context menu. Select the HTTP Headers tab. The Custom HTTP Headers box lists all of the.

Howard von Rooijen has a similar, more in depth account of removing the Server HTTP Header and other identifying headers via an HTTP Module when using IIS 7. See Cloaking. your ASP. NET MVC Web Application on IIS 7 for more details. Removing identifying response headers has two benefits. It slims down the quantity of data transmitted from the web server back to the browser, and. It makes it a bit harder for attackers to determine the software and their versions that are powering the web server. The Server, X Powered By, X Asp. Net Version, and X Asp. Net. Mvc Version HTTP headers provide no direct benefit and unnecessarily. Fortunately, these response headers can be removed with some configuration changes. Happy ProgrammingBy Scott Mitchell.

Agent String One of the things Id said Id do, Dear Reader, when I went to work for the Big Blue Monster, was to get your feedback into The Company whenever possible. Heres another opportunity for us to effect change, however small. A while back I made a little site called http www. Browsers User. Agentand let you know the size that the latest. NET Framework would be for you ballpark size. In the process Ive gotten to see a LOT of interesting Browser User. Agents in the IIS logs. If you visit the site and scroll down, youll see YOUR Browser User. Agent at the bottom. Heres mine Mozilla4. MSIE 8. 0 Windows NT 6. WOW6. 4 Trident4. SLCC1. NET CLR 2. NET CLR 3. 5. 2. 10. Media Center PC 5. Zune 2. 5 MS RTC LM 8. NET CLR 3. 0. 3. 06. Notice that Ive got IE8 on 6. Windows. However, theres other stuff in there, like I have the Zune software, I have Media Center enabled, and Ive got three versions of the. NET Framework. In this example, 2. Heres a User. Agent that showed up today on http www. Mozilla4. 0 compatible MSIE 7. Windows NT 5. 1 Mozilla4. MSIE 6. 0 Windows NT 5. SV1. NET CLR 1. Info. Path. 1. NET CLR 2. NET CLR 3. 0. 0. 45.

Now, this guy is clearly a developer who has installed beta versions of things, but hes also got Info. Path and a bunch of other stuff. Still, thats a pretty crazy User. Agent and its being transmitted all the time. User. Agents are added for IE in the Registry, as seen in the screenshot above. Why Should You CareIn the case of a system with IE and a lot of. NET Framework versions, ASP. NET currently truncates the User. Agent at 2. 56 characters so my own case, the site was only getting part of the story. They might change that truncation number, but ultimately, I think we all want tidy User. Agents, right User. Agent length matters. Early versions of Fire. Fox had a User. Agent Limit of 1. The Fire. Fox plugin added when you installed. NET by default only shows the most recent. NET Framework. Do you want that functionality in. NET Truncated User. Agents can also mean you might get Unknown Back from Request. Browser. Browser. In my case, I was getting an exception from Request. Browser. Clr. Version because the truncated CLR Version was something like. NET CLR 3. Theres some people looking at this internally, and theres three groups involved. Theres Internet Explorer, involved peripherally, theres the CLR Team and the installer that adds the values, and theres the ASP. NET team who cares because of the server side sniffing. PollQuestions. The questions I have for you are these Do you use these. NET Framework specific values What for How do they improve your site or make your user experience different If the. NET Framework specific values were removed completely what would that mean to you or your business What if the values were conflated to show just the most recent. NET Framework Could you get the information you needed using just the value of the latest version What if the values were conflated to show just the major side by side CLR releasesFor example, 1. SP1 and 4. 0. In that example, 3. SP1 implies 2. x and 3. If you just had 2. Could you get the information you needed using just the value of the those major CLRFramework versions Please take a moment and do this micropoll. Its ONE question with ONE vote button.
