How to enable blob cache in SharePoint 2013?

Blob cache is a disk-based caching technique. It will be extremely fast and eliminates the need for database round trips in SharePoint 2013. Blob Cache objects can be a image or sound or video file. BLOBs are retrieved from the database once and stored on the Web client. Further requests are served from the cache and trimmed based on security.

You can see this kind of message in SharePoint 2013 as below.

The blob cache is not enabled in this web application. Image renditions will not be generated until the blob cache is enabled. For information on turning on the blob cache, please review the product documentation.  

To enable the blob cache,

1. Open the web.config file
2. Search the "BlobCache" tag.
3. Change the "enabled" value as "true"

Thats it...

Multiple authentication pop up in SharePoint 2013


While learning SharePoint 2013, you might struggle to run your first application. For example, it may ask you to create the "App Domain" to deploy your SharePoint hosted "Apps". After creating the the App Domain, you will be able to view the "Apps" in "Site Contents" section in SharePoint 2013.

If you click on the "Apps", it will show a pop up to enter the user name and password.

This is because, you are not disabled the "loopbackcheck" in your development machine.


To disable that, just follow the steps from my another blog post, http://sensoft2000-sharepoint.blogspot.in/2010/07/error-access-is-denied-verify-that.html

Also, you need to add the App domain name in the "Local intranet" zone of the browser. The below image will show about how to add the URL in the browser.

Just start from "Security" tab & end with "Close" button. In the below example, I have added my app domain name as http://*.app.sensoft2000.com
