Re: Apache 2.2 mod_include mis-interpreting back-references

Hi Dan;

Yes, that silences the errors, thanks!

My question still remains - what changed in Apache that a construct it 
formerly parsed one way is now treated differently? Or not so much what 
changed, but why? Why does Apache now "care" what is inside an 'exec 
cmd' string?

Thanks again, now all I have to do is find all the darn docs to update 
them...
