Cache Container Tool

The Cache Container Tool (Cdcache.exe) is an AutoRun executable file that allows content outside of the cache to be associated with a specified URL, which can be referenced by Microsoft Internet Explorer 4.0. This tool allows you to assign a URL that will reference content from another directory or CD-ROM.

The tool creates a cache container in the Internet Explorer persistent URL cache. When a user enters the URL, the browser looks for the resource in the location specified by the cache container.

If an earlier version of Microsoft Internet Explorer is installed on the computer, a message appears, notifying the user that Microsoft Internet Explorer 4.0 is required, unless the /NoIE4Msg or /Silent command-line option is used.

The tool can be found in the \bin directory of the Internet Client SDK.

Usage

Use the following steps to install a cache container that references a CD-ROM:

  1. Create an Autorun.inf file.
  2. In the Autorun.inf file, enter the following text: 
    [autorun]
open=cdcache.exe
icon=cdcache.exe, 1

    If you want to use one of the Command-Line Options, add it to the open= line in the Autorun.inf file. The following example would install the cache container without displaying any user interface. 

    [autorun]
open=cdcache.exe /Silent
icon=cdcache.exe,1
  3. In the Autorun.inf file, add one or more entries to create a cache container. This section must contain less than 64K of data. It must be in the following format: 
    [Add.CacheContainer]
<Friendly Name>=<INF Section Name>

    The friendly name can be either the name of the company or the name of the product for which the cache container is being created. INF Section Name is the label you will use in the .inf file to define the details of your cache container.

    The following example shows an entry for two cache containers: one for Awesome Computers and one for Trey Research. 

    [Add.CacheContainer]
Awesome Computers=AwesomeComp
Trey Research=TreyResearch
  4. In the Autorun.inf file, add a cache container detail section for each cache container defined in the previous step. It must be in the following format: 
    [INF Section Name]
CachePrefix=<string>
CacheRoot=<relative path to the data>
KBCacheLimit=<numerical amount in KB>
AutoDelete=<Yes|No>
IncludeSubDirs=<Yes|No>
VolumeTitle=<string>
    CachePrefix Determines the URL pattern that the cache container will provide data for. For the cache container to work properly, the pattern cannot end with a backslash (/). For example, the URL pattern http://www.awesome_computers.com/ is incorrect. It must be http://www.awesome_computers.com to work properly. The same is true of patterns that include directories. For example, the URL pattern http://www.trey_research.com/awards/ must be set as http://www.trey_research.com/awards.
    CacheRoot Contains the relative path to the data provided by the cache container. The following replaceable parameters can be used for this entry:
    %EXE_DRIVE%
    Automatically replaced with the drive letter (including the colon) of the execution path of the Cdcache.exe tool.
    %EXE_ROOT%
    Automatically replaced with the full directory path of the Cdcache.exe tool.
    KBCacheLimit Contains the maximum number of kilobytes of data that can be stored in the user's local cache.
    AutoDelete Determines if the cache container data residing in the user's local cache should be purged after an interval (predetermined by Microsoft Internet Explorer 4.0) of non-use.
    IncludeSubDirs Specifies whether directories residing below the main CacheRoot= should be used to supply cache container data. Without this flag, only resources in the immediate CacheRoot= directory will be used to supply cache container data.
    VolumeTitle Contains the title or friendly name of the CD-ROM that the container was created for.

    The following example shows entries for two cache container detail sections. 

    [AwesomeComp]
CachePrefix=http://www.awesome_computers.com
CacheRoot=%EXE_DRIVE%\data\http\
KBCacheLimit=1000
AutoDelete=Yes
IncludeSubDirs=Yes

[TreyResearch]
CachePrefix=http://www.trey_research.com/awards
CacheRoot=%EXE_DRIVE%\data\http\awards\
KBCacheLimit=500
AutoDelete=Yes
IncludeSubDirs=Yes
  5. Place the Autorun.inf file at the root directory of the CD-ROM, which contains the content you want to register.

Command-Line Options

The Cdcache.exe tool supports the following command-line options:

/NoIE4Msg Disables the message that informs the user that Microsoft Internet Explorer 4.0 is required.
/Silent Installs all cache containers in the Autorun.inf file without displaying any user interface. This option will also cause it to fail silently.
/Remove Uninstalls all the cache containers listed in the Autorun.inf file.
/Uninstall Same as /Remove.
