Hi folks,

I'm in a tricky situation where I have a site with subfolders for differents brands like this :

https://my.umbraco.site/brandA
/brandB
/brandC
/brandD

and so on.

I have to migrate brandA on a new Umbraco site (newer version) on the same IIS server while keeping other brands on the original site. But for SEO reasons I must keep the same domain on this new site.To summarize, I'll have 2 sites under the same IIS sharing the same domain which is technically impossible.

To make it possible I used the method proposed here by Jonathan Maurer based on reverse proxy : https://our.umbraco.com/forum/umbraco-7/using-umbraco-7/74524-umbraco-in-child-virtual-directory#comment-280178

It's working nicely except for one thing : on the new site, images with query parameters in their name like https://my.umbraco.site/brandA/media/4cyhe4f4/1664.png?height=30 doesn't work (404 error) but work ok if I remove the parameter. I suspect that the rewriting prevents ImageProcessor to do his job.

Does anybody have any idea why and how I could fix that ?

Thanks in advance for your help, Arnaud
