always initialize the template
move the initialization to the proxy creation, and while here move the definition for the functions used by the template to fcgi.c too.
quick and dirty URL rewrite to respect SCRIPT_NAME
it's not really bad however
switch to the escaping function from tmpl.h
it also fixes some issue / limitations of the old htmlescape / printurl.
refactor proxy_read
- avoid the ugly `goto copy' to jump back to the start - avoid leaking memory
parse response MIME, check the charset and lang
If the charset is not UTF-8 nor ASCII then we don't know how to handle the body and so rejects it. An abset charset is implied to be utf8, so we're good. In the generated HTML we always use UTF8 charset, which is fine too, since it is a superset of ASCII. Attempt also at saving the lang for later reuse in the generated HTML.
