be auto filled with data from $Request->Form. This feature
requires HTML::FillInForm to be installed. Please see
the FormFill CONFIG for more information.
This setting overrides the FormFill config at runtime
for the script execution only.
=item $Response->{IsClientConnected}
1 if web client is connected, 0 if not. This value
starts set to 1, and will be updated whenever a
$Response->Flush() is called. If BufferingOn is
set, by default $Response->Flush() will only be
called at the end of the HTML output.
As of version 2.23 this value is updated correctly
before global.asa Script_OnStart is called, so
global script termination may be correctly handled
during that event, which one might want to do
with excessive user STOP/RELOADS when the web
server is very busy.
An API extension $Response->IsClientConnected
may be called for refreshed connection status
without calling first a $Response->Flush
This method could also be used to render other types of dynamic scripts,
like XML docs using XMLSubs for example, though for complex
runtime XML rendering, one should use something better suited like XSLT.
See the $Server->XSLT API for more on this topic.
=item $Response->IsClientConnected()
API Extension. 1 for web client still connected, 0 if
disconnected which might happen if the user hits the stop button.
The original API for this $Response->{IsClientConnected}
is only updated after a $Response->Flush is called,
so this method may be called for a refreshed status.
Note $Response->Flush calls $Response->IsClientConnected
to update $Response->{IsClientConnected} so to use this
you are going straight to the source! But if you are doing
a loop like:
while(@data) {
$Response->End if ! $Response->{IsClientConnected};
my $row = shift @data;
%> <%= $row %> <%
$Response->Flush;
}
Then its more efficient to use the member instead of
the method since $Response->Flush() has already updated
that value for you.
=item $Response->Redirect($url)
Sends the client a command to go to a different url $url.
Script immediately ends.
=item $Response->TrapInclude($file, @args)
Calls $Response->Include() with same arguments as

- Fixed 'application/x-www-form-urlencoded' for AJAX POSTs post
Firefox 3.x
+ First sourceforge.net hosted version
+ Incremented version number to actually match SVN branch tag
=item $VERSION = 2.61; $DATE="05/24/2008"
- updated for more recent mod_perl 2 environment to trigger correct loading of modules
+ loads modules in a backwards compatible way for older versions of mod_perl 1.99_07 to 1.99_09
+ license changes from GPL to Perl Artistic License
=item $VERSION = 2.59; $DATE="05/23/2005"
+ added "use bytes" to Response object to calculate Content-Length
correctly for UTF8 data, which should require therefore at least
perl version 5.6 installed
+ updated to work with latest mod_perl 2.0 module naming convention,
thanks to Randy Kobes for patch
+ examples now exclude usage of Apache::Filter & Apache::SSI under mod_perl 2.0
=item $VERSION = 2.57; $DATE="01/29/2004"
- $Server->Transfer will update $0 correctly
- return 0 for mod_perl handler to work with latest mod_perl 2 release
when we were returning 200 ( HTTP_OK ) before
now instead of $r->cgi_header_out. Added t/cookies.t test to
cover new code path as well as general $Response->Cookies API.
Also make cookies headers sorted by cookie and dictionary key
while building headers for repeatable behavior, this latter was
to facilitate testing.
- fixed $Server->Mail error_log output when failing to connect
to SMTP server.
+ added tests to cover UniquePackages & NoCache configs since this
config logic was updated
+ made deprecated warnings for use of certain $Response->Member
calls more loudly write to error_log, so I can remove the AUTOLOAD
for Response one day
- Probably fixed behavior in CgiHeaders, at least under perl 5.8.0, and
added t/cgi_headers.t to cover this config.
+ removed $Apache::ASP::CompressGzip setting ability, used to possibly
set CompressGzip in the module before, not documented anyway
-XMLSubs args parsing fix so an arg like z-index
does not error under UseStrict. This is OK now:
<my:layer z-index=3 top=0 left=0> HTML </my:layer>
-Only remove outermost <SCRIPT> tags from global.asa
for IIS/PerlScript compatibility. Used to remove
all <SCRIPT> tags, which hurt when some subs in globa.asa
would be printing some JavaScript.
+$Response->{IsClientConnected} now updated correctly
before global.asa Script_OnStart. $Response->IsClientConnect()
can be used for accurate accounting, while
$Response->{IsClientConnected} only gets updated
after $Response->Flush(). Added test cases to response.t
+$Server->HTMLEncode(\$data) API extension, now can take
scalar ref, which can give a 5% improvement in benchmarks
for data 100K in size.
-Access to $Application is locked when Application_OnEnd &
Application_OnStart is called, creating a critical section
for use of $Application
Buffering is enabled by default, as it is faster, and
allows a script to error cleanly in the middle of execution.
+more bullet proof loading of Apache::Symbol, changed the
way Apache::ASP loads modules in general. It used to
check for the module to load every time, if it hadn't loaded
successfully before, but now it just tries once per httpd,
so the web server will have to be restarted to see new installed
modules. This is just for modules that Apache::ASP relies on.
Old modules that are changed or updated with an installation
are still reloaded with the StatINC settings if so configured.
+ASP web site wraps <font face="courier new"> around <pre>
tags now to override the other font used for the text
areas. The spacing was all weird in Netscape before
for <pre> sections.
-Fixed Content-Length calculation when using the Clean
option, so that the length is calculated after the HTML
is clean, not before. This would cause a browser to
+Implemented $Response->{PICS} which if set sends out a PICS-Label
HTTP header, useful for ratings.
+Implemented $Response->{CacheControl} and $Response->{Charset} members.
By default, CacheControl is 'private', and this value gets sent out
every request as HTTP header Cache-Control. Charset appends itself
onto the content type header.
+Implemented $Request->BinaryRead(), $Request->{TotalBytes},
documented them, and updated ./eg/form.asp for an example usage.
+Implemented $Response->BinaryWrite(), documented, and created
and example in ./eg/binary_write.htm
+Implemented $Server->MapPath() and created example of its use
in ./eg/server.htm
-$Request->Form() now reads file uploads correctly with
the latest CGI.pm, where $Request->Form('file_field') returns
the actual file name uploaded, which can be used as a file handle
+ Switched to Big-endian date format in the documentation.

$Response->TrapInclude($file, @args)
Calls $Response->Include() with same arguments as passed to it, but
instead traps the include output buffer and returns it as as a perl
string reference. This allows one to postprocess the output buffer
before sending to the client.
