Hi [~wunder],
as written in my announcement mail, there is no way to disable the "dataConfig"
parameter in running installations, unless you completely disable DIH. So your
options are:
- disable DIH completely (yeah, not so nice)
- update to later version
- instruct your reverse proxy to remove "dataConfig" parameter before passing
to Solr. I have seen configs for nginx doing similar things with the
"stream.body" parameters.
- run Solr only on localhost
- install a firewall (that's a joke, you should have done this already)
