Sharepoint stop caching xml or media files

12/11/2009 Leave a comment

If  you are using sharepoint you noticed that every xml,img or media files are cached automatically. This is good for performance but its so problematic for changes or updates. You change something in your xml at background but users can not see changes because of sharepoint caching .

Solution is so easy

this is your file path:

[your xml url]/myfile.xml
[your img url]/img.jpg

if you change it like this

[your xml url]/myfile.xml?ver=[some number]

[your img url]/img.jpg?ver=[some number]

and after change your xml content generate some random number for [some number] sharepoint relaese caching your media or data files.I am using GUID for this 🙂

Getting Root Site in Sharepoint

12/11/2009 Leave a comment

When you are working in sharepoint with extended web applications which is using different authentication methods . You have to need current URL of different domain for hardcoded envoriment . For example http://www.test.com one of your extranet using forms authentication and http://myserver is your default and using windows authentication. if user create a request from http://www.test.com/somedifferet… you need to root of http://www.test.com rather than http://myserver.And you dont want a login screen because of links.

if you type hard code like this its not working for default domain which image not in _layout folder.

<img src=”http://myserver/something/imagenotcomingfromlayout.jpg”&gt; asks extra windows auth login

Solution.

<img src=”/_layouts/GetRootSite.ashx?url=http://myserver/something/imagenotcomingfromlayout.jpg”>

Handlers returns same as users coming request root site.and change http://myserver/ to http://www.test.com

Create a generic handler like below and add this handler to 12/TEMPLATES/LAYOUTS folder for every registered user can reach.

<%@ WebHandler Language=“C#” Class=“GetRootSite” %>

using System;

using System.Web;

using System.Net;


public class GetRootSite : IHttpHandler

{

public void ProcessRequest (HttpContext context) {

Uri requestUri = context.Request.Url;

string baseUrl2 = context.Request.Url.GetLeftPart(UriPartial.Authority);

string gelenpath = context.Request.QueryString[“url”];

Uri gelen = new Uri(gelenpath);

string gelenPreFix = gelen.GetLeftPart(UriPartial.Authority);

string artakalan = gelenpath.Substring(gelenPreFix.Length);

string sonuc = baseUrl2 + artakalan;

context.Response.Redirect(sonuc);

}

public bool IsReusable {

get {

return false;

}

}

}
