I use an
<img> tag with an src-attribute pointing to a script that loads the image from a non-public folder. When I test my website with a mobile connection, the scr-attributes path is changed from
src="http://184.108.40.206.bmi/example.com, I guess that has something to do with my mobile internet provider. The problem is, the image-providing script cannot identify the session of the incoming request anymore.
On a non-mobile WIFI connection, the src-attribute is not changed, everything works as expected and the session is found.
