Web caching commands

Web caching is supported only in RXX60P20 and later.

backup

Use backup to specify a backup Web caching slot.

Use undo backup to restore the default.

Syntax

backup slot slot-number

undo backup

Default

No backup Web caching slot is specified.

Views

Web cache view

Predefined user roles

network-admin

context-admin

Parameters

slot slot-number: Specifies an IRF member device by its member ID.

Usage guidelines

To enhance the high availability of Web caching, configure the Web cache backup feature. You can use this command to specify a backup Web caching slot. When the primary slot (specified by using the web-cache command) fails, the backup slot will take over to provide the Web caching service to ensure service continuity. When the primary slot recovers, the Web caching service switches back to the primary slot.

Examples

# Specify slot 1 as the backup Web caching slot.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] backup slot 2

cached-data

Use cached-data to specify the types of the webpage files to be cached.

Use undo cached-data to restore the default.

Syntax

cached-data { apk | bmp | doc | docx | gif | gzip | ipa | jar | jpg | jpeg | mp4 | pdf | png | ppt | pptx | rar | swf | tar | txt | xls | xlsx | zip } *

undo cached-data

Default

No webpage file types are specified.

txt: Specifies .txt files.

xls: Specifies .xls files.

xlsx: Specifies .xlsx files.

zip: Specifies .zip files.

Usage guidelines

If you do not specify the types of the webpage files to be cached, the Web caching feature does not cache any types of files on webpages.

Execute this command before enabling Web caching.

Before configuring or modifying file type settings, you must disable Web caching. After configuring or modifying file type settings, enable Web caching again.

Execution of the undo cached-data command will not delete webpage files saved in the Web cache directory. The Web caching feature can still cache webpage files specified by using the cached-file command.

Examples

# Configure the Web caching feature to cache .doc and .docx files on webpages.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] cached-data doc docx

context-admin

Parameters

file-name: Specifies a webpage file by its name, a case-sensitive string of 1 to 127 characters.

Usage guidelines

You can repeat this command to specify multiple webpage files to be cached.

If you specify both webpage files and types of the webpage files to be cached, the device caches the matching webpage files of the specified types.

Before you add or delete a webpage file to be cached, you must disable Web caching. After adding or deleting the webpage file, enable Web caching again.

Execution of the undo cached-data command will not delete webpage files saved in the Web cache directory.

Examples

# Specify file test1.doc as a webpage file to be cached.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] cached-file test1.doc

Related commands

cached-data

cache-limit

Use cache-limit to set the maximum total size for Web cache files.

Use undo cache-limit to restore the default.

Syntax

cache-limit size

undo cache-limit

Default

The maximum total size of Web cache files is 4 GB.

Views

Web cache view

Predefined user roles

network-admin

context-admin

Parameters

size: Specifies the maximum total size for Web cache files in GB. The value range is 1 to 4095. The default is 4.

Usage guidelines

Before changing the maximum total file size setting, you must disable Web caching. After changing the maximum total file size setting, enable Web caching again.

The maximum total size for Web cache files must be smaller than the maximum storage space size in the working directory. To display the maximum size of storage space in the working directory, execute the display web-cache command. After the effective maximum total size is reached, the device deletes the oldest Web cache file to save the new Web cache file.

The aging time for Web cache files is fixed at 30 days. When the device reboots or receives a request for the content in a Web cache file, it restarts the aging timer. If no users request the content in a file before the aging timer expires, the device deletes the file.

Examples

# Set the maximum total size for Web cache files to 3 GB.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] cache-limit 3

display web-cache

Use display web-cache to display Web caching information.

Syntax

file-directory

Use file-directory to set the primary Web cache directory.

Use undo file-directory to restore the default.

Syntax

file-directory directory

undo file-directory

Default

The primary Web cache directory is not set.

Views

Web cache view

Predefined user roles

network-admin

context-admin

Parameters

directory: Specifies the primary Web cache directory, starting from the storage medium location information slotn#. The slot number n must be the same as the slot number of the Web cache view.

Usage guidelines

Before changing the Web cache directory, you must disable Web caching. After changing the Web cache directory, enable Web caching again.

Make sure the storage medium where the Web cache directory resides has sufficient storage space. The Web caching feature saves its operation data and the Web content to be cached to files in the directory. The directory typically needs a storage space of over 1 GB.

Before specifying a Web cache directory, make sure all files in the upper-level directory are using a different name than the Web cache directory or have a file extension. For example, if you want to specify flash:/web-cache as the Web cache directory, files without a file extension in the flash: directory cannot use web-cache as the file name.

The primary Web cache directory for a Web cache view must reside on the same slot as the Web view.

Examples

# Set the primary Web cache directory.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] file-directory slot1#flash:/aaa

file-directory backup

Use file-directory backup to set the backup Web cache directory.

Use undo file-directory backup to restore the default.

Syntax

file-directory backup directory

undo file-directory backup

Default

No backup Web cache directory is set.

Views

Web cache view

Predefined user roles

network-admin

context-admin

Parameters

directory: Specifies the backup Web cache directory, starting from the storage medium location information slotn#. The slot number n must be the same as the slot number of the Web cache view.

Usage guidelines

To implement Web cache backup, use this command to specify the backup Web cache directory. When the device uses the primary slot for Web caching, it saves webpage files to the primary Web cache directory. When the device uses the backup Web caching slot, it saves webpage files to the backup Web cache directory.

Make sure the storage medium where the Web cache directory resides has sufficient storage space. The Web caching feature saves its operation data and the Web content to be cached to files in the directory. The directory typically needs a storage space of over 1 GB.

The backup Web cache directory for a Web cache view must reside on the backup slot. After the backup Web cache directory is created, the device will not synchronize cache files under the primary directory to the backup directory.

Before specifying a Web cache directory, make sure all files in the upper-level directory are using a different name than the Web cache directory or have a file extension. For example, if you want to specify flash:/web-cache as the Web cache directory, files without a file extension in the flash: directory cannot use web-cache as the file name.

Before changing the Web cache directory, you must disable Web caching. After changing the Web cache directory, enable Web caching again.

You must specify a directory on the slot same as the backup Web caching slot specified by using the backup command.

Examples

# Set the backup Web cache directory.

<Sysname> system-view

[Sysname] web-cache slot 1

[Sysname-web-cache-slot1] file-directory backup slot4#flash:/webcache
