在Apache 2.4中删除了带有下划线的所有大写HTTP标头

Question

I have an app that relies on sending all-caps-with-underscores HTTP headers along with a request.

Starting with Apache 2.4,

Headers containing invalid characters (including underscores) are now silently dropped

This page suggests there are settings you can change that would allow legacy HTTP headers that aren't stripped (i.e., if they're set in CURL, then they would show up in the $_SERVER array in PHP) but it doesn't say how. I tried adding the following to my HTACCESS file,

SetEnvIfNoCase ^Accept.Encoding$ ^(.*)$ fix_accept_encoding=$1 RequestHeader set Accept-Encoding %{fix_accept_encoding}e env=fix_accept_encoding

but it didn't seem to help. Has anyone else experienced this when moving from Apache 2.2 to 2.4?

Not sure how much access you have to the machine. But you could use PHP to check for the modules

print_r(apache_get_modules());

If you have mod_setenvif and mod_headers your .htaccess rules should be fine
