[users@httpd] RequestHeader can not match single space char?

[David Balažic <da...@comtrade.com>]

Hi!

I have apache 2.4.7-1ubuntu4.9  (on Ubuntu 14.04.4 64bit) and while this works:
RequestHeader edit Some-Header " M" "X" 

This does not:
RequestHeader edit Some-Header " " "X" 

Am I missing something obvious?

The first one matches a pair of space and capital M and replaces them with X.
The later does not seem to do anything (to the same test data).
I also tried using "\s", but it also does not seem to work.

Help!

Pilot error!

edit replaces one occurence of the string, while edit* replaces all of them.
I had a long string with many spaces and missed that the first space was replaced and only noticed the others still being not replaced.

Over-and-out,
David
