This is very interesting problem and I thought the issue was the typo leaving your var empty. I'll have to do some research about the mod_rewrite myself to confirm it precedes SetEnvIf in the order of execution.
Now I'm really curious about the solution my self and will try to find some explanation even test this on one of my apaches if i find time to do that. Have you tried this: Header add X-Debug-Request-URI "%{REQUEST_URI}i" i think the difference is that the character "e" at the end means output value and "i" means the input value of the REQUEST_URI. If that doesn't work try putting the 'Header add " statement before RewriteRules'' Igor On Fri, Mar 23, 2012 at 10:39 AM, Bruno Tréguier <bruno.tregu...@shom.fr>wrote: > Le 23/03/2012 à 0:23, Bruno Tréguier a écrit : > > 1) the X-Debug-Request-URI header is correct in the HTTP response, >> example: >> >> X-Debug-Request-URI: /cartes-en-ligne/checkout/ >> >> 2) the X-CheckingOut header, however, is NOT set. :-( >> > > Sorry, that was another test.
