Get Server Type.

Copy linkTweet thisAlerts:
Mar 23.2009

Hello all. I am new here, so please bear with me.

I have an app that contains both VBscript and Javascript. I need to be ablel to use javascript to determine the Sever Type (IIS or NON IIS) to direct users to the correct pieces of code to run given a certina situation.

I know how to do this with vbscript, but if this site gets hosted on Apache as well (which we think is likely), we need the server type.

Thanks.

@FangMar 23.2009 — JavaScript can not get server information, that requires a server side language.

@ZeroKilledMar 23.2009 — unfortunately, or fortunately, javascript don't have any kind of access to http header of document sent to browser. that is, if you load the document [noparse]mysite.com/index.html[/noparse] in browser, there is no such property (or similar) in javascript as [b]document.headers, document.getHeaders()[/b]. nothing.

however, you can use XHR (XMLHttpRequest) and request a single file, it can be empty and then read the header 'server':
<i>
</i>var xhr = new XMLHttpRequest();
xhr.open('get', '/file.txt', true);
xhr.send(null);
var server = xhr.getHeader('Server');


you will get a string that identify the server. the code is just for demonstration purpose, you have to fix it according to the browser.

Success!
