Changes to Squid-2.1 (November 16, 1998):
- Changed delayPoolsUpdate() to be called as an event.
- Replaced comm_select FD scanning loops with global fd_set
structures. Inspired by Jeff Mogul's patch for squid 1.1.
- Moved functions common to dns.c, redirect.c, authenticate.c,
ipcache.c, and fqdncache.c into helper.c.
- Changed storeClientCopy2() so that it keeps sending the remainder
of a STORE_ABORTED request, instead of cutting off the client as
soon as the object becomes aborted.
- Fixed combined ipf-transparent proxy and a local http-accelerator
operation (Quinton Dolan).
- Rewrote base64_decode.c because of potential buffer overrun
bugs.
- Configurable handling of whitespace in request URI's.
See 'uri_whitespace' in squid.conf.
- Added ability to generate HTTP redirect messages from
the redirector output by prepending "301:" or "302:" to the
new url. See FAQ 4.16 for more details.
- Eliminated refreshWhen() which was out-of-sync with refreshCheck()
potentially causing under-utilized cache digests
- Maintain refreshCheck statistics on per-protocol basis so we
can tell why ICP or Digests return too many misses, etc.
- Fixed delay_pools.c class2/class3 typo (Simon Woods).
- Changed squid.conf's default access controls to deny all
HTTP requests. Admins must write ACL rules to specifically
allow their local clients.
- Patched French error messages (Mathias HERBERTS).
- NextStep porting fixes by Mike Laster:
- use xstrdup() in cf_gen.c
- check for putenv() in configure
- #define S_ISDIR macro
- Added --disable-poll configure option (Henrik Nordstrom).
- Fixed internal URL hostname case bugs (Henrik Nordstrom).
- Patched ftp.c so we never cache autenticated FTP requests
(Henrik Nordstrom).
- Fixed FTP authentication. We tried to unescape authentication
given by basic authentication which is not URL escaped
(Henrik Nordstrom).
- Fixed HTTP version for common logfile format (Henrik Nordstrom).
- Added 'redirect_rewrites_host_header' option to disable rewriting
of Host header for redirector responses (Henrik Nordstrom).
- Allow semi-customized error message signatures (Henrik Nordstrom).
- Fixed bug with errors for unsupported requests (Henrik Nordstrom).
- Fixed handling of blank lines in ACL input files (Henrik
Nordstrom).
- Changed proxy_auth ACL type to consist of a list of valid
users. REQUIRED == any (same as ident ACL). ACL type user
changed to ident since this is what it really is.
(Henrik Nordstrom).
- Fixed long URL bugs; make sure 'log_uri' never exceeds
MAX_URL bytes.
- Allow comments in external ACL files (Gerhard Wiesinger).
- Added 'range_offset_limit' configuration option. Requests
with ranges that start after this value will be passed
on unmodified, and Squid will not cache the response
(Henrik Nordstrom).
- Added Client HTTP Hit byte counters to 'counters' output
(Douglas Swarin).
- Got Squid to compile with --enable-async-io on FreeBSD.
- Fixed infinite loop bug for cachemgr 'config' option.
- Fixed cachability bugs for replies with Pragma: no-cache.
- Made content-type multipart/x-mixed-replace uncachable.
- Y2K fix for parsing dates in "Wed Jun 9 01:29:59 1993 GMT"
format (Richard Kettlewell).
- Fixed passing -s option to dnsserver processes (Alvaro Jose
Fernandez Lago).
- Changed proxy_auth to work on internal objects and when in
accelerator mode. (Henrik Nordstrom)
- Added login=user:password option to cache_peer directive to
be used from a dial-up cache where the parent requires proxy
authentication. (Henrik Nordstrom)
- If you want to "auto-login", then use a URL on the form
http://username:password@server/.... Squid now picks this up
when going direct, and turns it into basic WWW
authentication. It is also possible to do automatic login to
certain servers by using a redirector to add the needed
authentication information. (Henrik Nordstrom)
- Changed refreshCheck() so that objects with negative age
are always stale.
- Fixed "plain" FTP listings (Henrik Nordstrom).
- Fixed showing banner/logon message for top-level FTP
directories (Henrik Nordstrom).
