I moved my installation from the old stable 0.7.x branch to the new  
stable 0.8.x and cannot proceed as I get an error message saying  
proxy\_cache\_bypass must be used along with proxy\_no\_cache since v0.8.46.  
However, it seems proxy\_cache\_bypass is not documented anywhere (can’t  
find it on the wiki anyway apart from one statement in the 0.8.46  
changelog listing it as a new feature).

Can anyone kindly point me to where I can find documentation on this?

Thanks

It’s not “must”, but to achieve the same effect it should.

proxy\_no\_cache now means “don’t store results into cache”  
proxy\_cache\_bypass means “don’t return results from cache”

Both have the same syntax.

In Russian it’s here:
