2.20.500

2.20.500 is 2.20 Rev 2 and is an official stable release, the current beta is further below. The installer has been updated with this version as well.
The downloads below are just the base ihtml.dll and ihtml.so files. You must have ihtml already installed and configured to use these Revision updates. We STRONGLY recommend you download the installer or run your existing installer (which will autoupdate) to install these updates to get all the components correctly.

Note to Linux and FreeBSD users: the iHTML Apache interface has been renamed to follow apache module naming conventions. If you have a reference to "AddModule s_apache.c" in your httpd.conf, rename it to "AddModule mod_ihtml.c".

Windows NT/2000/XP Files (Rename these to ihtml.dll and replace your existing file, you need to stop the web server to do this

IIS (all versions), WebSite Pro, Zeus, iHTMLAdmin
Netscape Enterprise 3.x
Apache 1.3.6
Apache 1.3.12 to 1.3.22
Apache 1.3.23 & Up

Note: Inline has dropped support for Solaris, BSDi (not FreeBSD) and Windows 95/98 operating systems to enable us to focus on the core three operating systems. We have also dropped support for Netscape web servers. Any questions or concerns can be addressed to russc@inline.net

For the iHTML Enterprise Plus Edition, updated (Sep 14th 2005) documentation is available Here as an RTF file.


2.20.1601

The following is a release candidate 8 version. Please report any issues you find. Also check your FORMMULTIVALUE setting in iHTML, in general it should be FALSE.
If you are not using GLOBAL variables then add and set the registry entry USEGLOBALS to FALSE in HKLM/software/inline/ihtml/currentversion/ Also if you have MinYieldTime set to anything other than 0, set it to 0. Both of this could dramatically increase the speed of your system.

Last Update of program files: Jan 29th, 2007. The version number is 2.20.1601

For Linux and FreeBSD you need to also ensure some standard library files are installed on the machine. These libraries are now dynamically loaded to ensure compatibility between iHTML and other apache modules on your system. The following libraries need to be installed: libgd2, libfreetype6, libpng3, libjpeg62.

Source:
libgd2 (libgd 2.0.28+ - http://www.boutell.com/gd/) * compile this after installing the three below
libpng3 (libpng 1.2.x - http://www.libpng.org/pub/png/libpng.html)
libfreetype6 (freetype 2.x - http://sourceforge.net/project/showfiles.php?group_id=3157)
libjpeg62 (jpegsrc.v6b - http://www.ijg.org/)

Linux:
Packages are found in RPM or Deb format in your Linux distribution. Preferably install them from your distribution media.
On RPM systems: <locate the rpm files> and 'rpm -Uvh file1 file2 ...'
On Debian systems: 'apt-get install package1 package2 ...'

FreeBSD:
libpng.so.5 (on FreeBSD 4.10 in the package graphics/png-1.2.5_3.tgz)
libgd.so.4 (on FreeBSD 4.10 in the package graphics/gd-2.0.22,1.tgz)
libjpeg.so.9 (on FreeBSD 4.10 in the package graphics/jpeg-6b_2.tgz)
libfreetype.so.9 (on FreeBSD 4.10 in the package print/freetype2-2.1.7_3.tgz)

July 29th, 2004

  • Multi-valued form variables such as checkbox groups missed some values that are submitted out of sequence. Eg. a form submission “a=1&a=2&b=3&a=4” turned into a variable a=1,2 instead of a=1,2,4.

Use BOUNDARIES=true to get a date difference by counting the number of date unit boundaries that are crossed between two dates, similar to how database datediff functions work.
  • iPOP tags now properly return multiple line headers
  • ihttpsession - working with https
  • iREDIR improvement to the status directive
  • /!ihtml - handles status changes now as well
  • iMULTIPART handles boundry info not in quotes now

  • plus lots of little things that unfortunately got fixed but not noted or where fixed as a result of another fix.

New Features

1. GZIP result pages
What this does is compress the result page before sending it to the browser if it will accept that format. This means that bandwidth can be cut by as much as 50% on your dynamic pages.

2. iHTML Scoreboard
This is a very handy new tool that allows you to view in realtime the currently processing ihtml pages and when they started. It can be used to track down if something is stuck or taking a long time.
Get the file to use with this feature Here
To enable this add an entry to HKLM/software/inline/ihtml/currentversion called scoreboardpath with a value of a path such as c:\ihtml\scoreboard\ and also an entry called scoreboard with a value of TRUE.
3. iHTML as an XML server
Currently the XML tags allow iHTML to act as an XML client but new functionality will allow it to act as an XML server as well. There have been other significant improvements to the XML tags to handle SOAP better among other things.

4. SQL insertion prevention
This is the ability to prevent malicious SQL statements from being inserted in query strings and post data. Default is off but it can be turned on if needed.

5. New Error Variables
i_error_ssl
i_error_xml
i_error_smtp
i_error_httpsession
i_error_cryptolib
i_error_nslookup

5. New URL Variables
ihtmlpagerequest->ihtmlpagerequest.request.protocol
ihtmlpagerequest->ihtmlpagerequest.request.hostname
ihtmlpagerequest->ihtmlpagerequest.request.port
ihtmlpagerequest->ihtmlpagerequest.request.hostip
ihtmlpagerequest->ihtmlpagerequest.request.uri
ihtmlpagerequest->ihtmlpagerequest.request.query

The above format can be used for an variables in any XML structure within iHTML. The text before the -> is the ALIAS name of the XML structure.

You can also get at these variables with the iXML tags
<ixmlquerytagbody alias=ihtmlpagerequest tag=ihtmlpagerequest.request.hostname>
You can also dump out the entire request structure using
<iXMLToFile ALIAS="ihtmlpagerequest" PATH="ihtmlpost1.xml">

bug in iRESUME


Things that are not bugs or can't be addressed:

iPEEK/iPUSH on IE: These show the headers in the page. This is because the web server IIS and WebSite Pro (not Apache) send duplicate headers to the browser. Netscape browser handles this ok but IE doesn't. There is nothing iHTML can do to get around this issue unfortunately as far as we have been able to determine because it is the web server sending the extra headers.
