Unyson not playing nice with Varnish-caching

[warudin]

Unyson uses session_start() on some places, which apparently causes Varnish-caching to fail for us.

Did someone else get Varnish working with a site running with Unyson? Is there something that can be done about it?

can you try this branch? https://github.com/ThemeFuse/Unyson/tree/sessions

[warudin]

I've added the changed file and as far as I can see this works.

@warudin I reverted commits so unyson will continues to use sessions. Now forms messages not work with this branch; I have to think of another mechanism. Try to enable sessions or keep the current file version after next update of unyson.

The link doesn't work anymore, can anyone give me the fix for this? I am getting the following from my hosting company::
"After reviewing this issue for you, it appears there is a conflict with your Unyson plugin that is preventing the server from caching properly.
I tested this by disabling the Unyson plugin temporarily and running the
command: wp varnish debug from within your domain's directory. With the
Unyson plugin disabled, the server caches the site properly without any issues.
In this case, I would recommend reaching out to the Unyson plugin developers to determine if there is a workaround to allow that plugin to work with the nginx server cache, or alternatively, you may want to look into a different plugin which would be more compatible."

@badgerland: as can be seen in the last message of @ViorelEremia, the changes have been reverted because of problems. ViorelEremia would think about another solution, but as the ticket has been closed, I don't think that there will be any follow-ups.

That being said, the ticket shouldn't remain closed since the changes have been reverted and thus the problem hasn't been solved.
