[mod_python] mod_python, HTTP headers and CRLF

HI!

I experienced some problems with sending HTTP headers. I'm
generating HTTP header lines separated with \r\n since HTTP standard
1.0 says in section 4.2 "Message Headers":

----------------------------- snip ------------------------------
       HTTP-header    = field-name ":" [ field-value ] CRLF
----------------------------- snip ------------------------------

In apache.py class CGIStdout method write() the headers are splitted
by using \n\n as separator which fails if scripts are sending header
conform to HTTP specs above. Here's a patch by using \r\n\r\n as
second possible
separator:

----------------------------- snip ------------------------------
395a396,400
> 
>             if len(ss) < 2:
>               # Second try with splitting by using \r\n\r\n as separator
>               ss = string.split(self.headers, '\r\n\r\n', 1)
> 
----------------------------- snip ------------------------------

Would be nice if this patch makes its way into the mod_python
distribution.

Ciao, Michael.
