   Please clarify what you mean with parameters. By the WMS standard:

   6.4 Request Parameter Rules
   6.4.1 Parameter Ordering and Case
   Parameter names shall not be case sensitive, but parameter values shall be case sensitive.
   In this document, parameter names are typically shown in uppercase for typographical
   clarity, not as a requirement.

   It means that by the standard only "WMS" should be accepted as a service name, but &SerVICe=WMS is OK. Most, but not all, WMS servers accept also "wms".

   Do you know some client that does not follow the standard? Or does MapCache change some parameter values into upper case?

   Yes, I have encountered WMS services that do not follow the standard, when I use &service=wms I can request successfully, but not when &SERVICE=WMS.

   The primary action would be to ask if they could make a fix on their side. It also fits with the robustness principle https://en.wikipedia.org/wiki/Robustness_principle.

   There are infinitely many ways how a non-conformant server can behave and thus it is impossible to support non-conformant servers as infinitely many workarounds would have to be implemented. This is the reason why we do have standards and follow them.
