Issue with Adobe campaign while targeting larger recipient

[priya_vinoth]

We get error while sending large-scale mailings, The common thread seems to be hosting location https://www.elsevier.com/__data/assets/image/. The same image work fine with the large scale campaign if we change the host to http://media.journals.elsevier.com/content/files/.

we found something like below screen grab when I downloaded files from both domains

Images served by https://www.elsevier.com/__data/assets/image/ do not have a Content-Length header, will this be a root cause to produce error with large-scale campaign execution, kindly advise? 

if so do we need to update adobe configuration?

If adobe able to execute campaign with the domain http://media.journals.elsevier.com/content/files/, then it should be able to run with other domain also right?

But what kind of error are you getting on campaign?

anyways,

I've compared both assets and the one served by https://www.elsevier.com does not have the content length header as you are aware, also it seems that no assets served by elsevier have the content-length header set as you can see from the following next example:

https://www.elsevier.com/__data/assets/file/0017/1137050/0023-add-on-boarding.svg

Elsevier uses Squiz Matrix CMS which runs on Ngix with Openresty Bundle, if you think that content-length header is the issue, then you need to ask the CMS host (SQUIZINC-NYC) if they can add it in the server configuration as is not hosted on premise but rather by Squiz themselves.

Does the Content-Length header/entity is mandatory to run html in Adobe campaing?
