insert space among headers when loading external domain fragment.

[ufaria]

i'm using version 6.0.0.9 and when trying to include an external domain fragment, the mod_esi are including extra spaces among http headers.

when the fragment is from local domain it works correctly.

i could see it using tcpdump. The spaces among headers are inserted by mod_esi. ... 12:43:05.702149 IP 3.4.5.6.37920 > 6.7.8.9.80: tcp 1684 GET /testurl.html HTTP/1.1 Host: www.someexternaldomain.com
