While sending paramters of called cgi script from working thrad to cgid serwer
by socket '\n' char is used to separate each part. If in sending enviroment '\n'
char will be used, all parameters will be send bad, some enviroment elements and
- what worst - every PUT variable will be lost. This bug making cgi scripts
which are working in SSL enviromend and which need SSL information unusable. 
Maybe this patch to mod-cgid.c will help:
