Dispatcher caching issue while displaying the image renditions in Adobe Experience Manager(AEM)

We are using the image renditions to display the images for different devices in Adobe Experience Manager(AEM).

The HTML5 Adaptive image is used as shown below to display the images for different devices.

<img src="/content/dam/Albin/Untitled.jpg" srcset="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png 1x,/content/dam/Albin/Untitled.jpg" alt="Sample Image">

/content/dam/Albin/Untitled.jpg - Original image
/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png - Rendition for 1x devices.

If the image is first accessed from the mobile devices then Untitled.jpg folder is created to cache the renditions image(rendition images will be matched for mobile devices) - /content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png

While the image is getting accessed from desktop browsers then dispatcher will try to return the folder Untitled.jpg as image(/content/dam/Albin/Untitled.jpg - original image will be matched for desktop browsers) so the image link will be broken in browser.

In other hand, if the image is first accessed from desktop browser then dispatcher caches Untitled.jpg as image. The subsequent request to the renditions image will not find the images in dispatcher cache so the image will be retrieved from publisher for rendering(rendition images will not be cached in this scenario as untitled.jpg is created as a image).

How to enable SSH X11 forwarding in Linux?

How to enable SSH X11 forwarding in Linux?

The  X11 forwarding from putty using Xming was not working, the DISPLAY variable is not set(echo $DISPLAY) after opening the remote server session in putty(X11 forwarding is enabled in putty and also the display is specified as localhost:0.0)

The actual issue is the X11 forwarding was not enabled in remote linux server.

The following steps can be followed to enable the X11 forwarding in linux server.

Login to linux server through putty

vi /etc/ssh/sshd_config

Enable the following flags

AllowAgentForwarding yes
AllowTcpForwarding yes
X11Forwarding yes

Execute the following commands

service sshd restart

yum -y update xauth
yum -y install xauth

Now you will be able to perform X11 forwarding.
