getImageURL is generating only the relative URl and not full URL including server name

HI All,

We are using "getImageURL" peoplecode to generate the URL to the image.

it is generating URL like below in one environment-

<img src="/cs/findev/cache/IMAGE_EMAIL_24.PNG">

Whereas in other environment it working fine as below-(expected)

<img src="https://servername.domainname.com/cs/findev/cache/IMAGE_EMAIL_24.PNG">

You insights into it will help as to why it is not generating the full URL.

Regards,
Neetesh
