[imp] The page cannot be displayed - problem

[Son Truong]

Hello Joseph

Thanks for the reply - I didn't think anyone would... I had the same 
speed issue (with apache running SSL - forgot to say in the first post) 
the last time  I set up  the new Webmail (H3) and had asked here...

I did a search of the mailing list and came up with a post date 2005!

And I followed the above advice (SSLCipherSuite and the SetEnvIf) and 
this _seem_ to solve the problem for the time being... If this fix the 
problem it should be put in the FAQ.

I will, for sure, follow your advice and look at apache2 tuning further 
as I still have 'speed' related issue with regards to my setup (and I 
have tried to implement all that is possible that is suggested in the 
PERFORMANCE document).

Thanks again,
Son Truong
