When there is a server redirect, POST requests without login don't work correctly

[SanjaJasek]

We set up a 307 redirect from server1 to server2. Everything works as expected, except POST requests with no login, e.g.
catmaid_fetch(path = "/11/connectors/links/", body = list(skeleton_ids=1634001, relation_type="desmosome_with"))
GET requests still work even for no login.
I'm pretty sure the problem is similar to Commit 3ecec5f. But I'm not sure how to fix it. Could you please help with this?

@SanjaJasek it's a long time since I've thought about this unfortunately. @tomka can you give any input?
