[Checkins] SVN: zope.publisher/trunk/src/zope/publisher/http.py Fix caching issue. The input stream get never cached in a temp file

[Roger Ineichen]

Log message for revision 76188:
  Fix caching issue. The input stream get never cached in a temp file 
  because of a wrong content length header lookup. Added CONTENT_LENGTH 
  header check additional to the previous used HTTP_CONTENT_LENGTH. The 
  HTTP_ prefix is sometimes added by some CGI proxies but CONTENT_LENGTH
  is the right header info which should know the size
