Subject Re: Reading a prameter set in browser in request handler
Date Sun, 02 Oct 2016 19:27:40 GMT
We have a different problem, then.

Accessing Solr directly from the web is a very, very bad idea. Solr is not designed for hostile
web access. I’m glad to share with you a simple command that will delete all the documents
in your index. Works great.

So step #1 is to put some kind of server between the browser and Solr. That server can make
substitutions. Or you can have a request handler for each locale.
