purpose of OC_X_REQUEST_ID ?

[hannesa2]

A general question concerning

android-library/src/com/owncloud/android/lib/common/OwnCloudClient.java

Line 175 in d49814c

addHeaderForAllRequests(OC_X_REQUEST_ID, RandomUtils.generateRandomUUID());

Why do it needs a unique number OC_X_REQUEST_ID here and client don't save or handle it.
So from the client side there is no need doing it here. That means only server needs it ?
If yes, the server can give himself the number too ?

@hannesa2 see related owncloud/android#2055

The client should write the X-REQUEST-ID to the log. It is also shown in the owncloud.log from servers 10.0.4+ and it can de displayed in the web server logs and in debug logs from infrastructure like loadbalancers or firewalls. This way it's easier to debug issues that result in weird client behaviour, but are caused by server misconfiguration or buggy infrastructure.

To make it work properly, you need #201
