Dear Jarno, Thanks for the feedback on this.
I investigated further to find the solution to this issue. It turned out that not all PUT requests had a problem with filtering out the customerId parameter we're looking for.
Some requests seem to encode the HTTP PUT body somehow or have set some HTTP header which prevents haproxy from extracting the parameter.
I'm still trying to find out what exactly is different. Best Simon Am 14.05.2018 um 14:40 schrieb Jarno Huuskonen:

Are the POST/PUT requests large, is it possible that the customerId doesn't fit in haproxy buffer (default 16k (I think)) ? Can you test with curl to see if customerId is logged then: curl -v -X PUT -d'customerId=911' http://yourhost.yourdomain/yourpath # bigfile is some random file much larger than 16k and curl -v -X PUT -d@bigfile -d'customerId=912' http://yourhost.yourdomain/yourpath -Jarno
