Hi Salifou,
OK, i see now, then you have two options:
a) To extend the sdk:
1. extend java-sdk by allowing to inject custom headers in every request=C2=
=A0(not trivial as all ovirt SDKs are auto-generated,but if its common case=
, you may find yourself getting help from community/maintainers)
2. fork java-sdk customizing it for your needs
I'd recommend the former as fork will leave you with no support/maintenance=
 from community plus you'll haveto implement new=C2=A0features by your own =
(what will become a moving target very quickly)=20
b) Proxying the sdk
You can implement dynamic proxy wrapping SDK's HttpProxy.java#execute and i=
ntercept the context from there,but you've to stay tuned as backward compat=
ibility is for interface and not for SDK internals,so "potentially" you can=
 find your code broken in one of the following upgrades
hope it helps.=C2=A0

 Hi Micheal,

Thanks for replying. Unfortunately the headers are dynamic ...

Here is the story:

We implemented a custom RHEV-M AAA module for a client
in order to allow their custom portal to make RHEV-M API=20
calls.=20

The custom AAA module requires extra dynamic data in the HTTP=20
request (as request headers for now but request parameters=20
should be fine too).=20

Their is no problem if they go with the REST API, I am just=20
trying to anticipate/identify potential integration problem ...

It seems like they will have to use the REST API or modify the=20
java sdk ...=C2=A0=20

Thanks a lot,
Salifou

Hi=C2=A0Salifou,
Actually java sdk is=C2=A0intentionally=C2=A0hiding transport level interna=
ls so developers could stay in java domain,if your headers are static, easi=
est way would be using reverse proxy in a middle to intercept requests,=C2=

can you tell me why do you need this?

 Hi Micheal,

I have a question about the ovirt-engine-sdk-java.

Is there a way to add custom request headers to each RHEVM API call?

Here is an example of a request that I would like to do:

$ curl -v -k \
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -H "ID: user1@ad.xyz.com" \
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -H "PASSWORD: Pwssd" \
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 -H "TARGET: kobe" \
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 https://vm0.smalick.com/api/hosts

I would like to add ID, PASSWORD and TARGET as HTTP request header.=20

Thanks,
Salifou
