Managing the Cache URL List

The proxy has a utility called urldb that manages the URL list in the cache. You can use this utility to list the URLs that are cached. You can also selectively expire and remove cached objects from the cache database.

The urldb commands can be categorised into three groups based on the -o option:

• domains

• sites

• urls

To list domains, enter the following at the command line:

urldb -o matching_domains -e reg_exp -d conf-dir

For example:

urldb -o matching_domains -e “.*phoenix.*” -d server_root/proxy-serverid/config

where

• matching_domains lists domains that match regular expression

• reg_exp is the regular expression used

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config.

To list all the matching sites in a domain, enter the following at the command line:

urldb -o matching_sites_in_domain -e reg_exp -m domain_name -d conf-dir

For example:

urldb -o matching_sites_in_domain -e “.*atlas” -m phoenix.com 
	-d server_root/proxy-serverid/config

where

• matching_sites_in_domain lists all the sites in a domain that match the regular expression

• reg_exp is the regular expression used

• domain_name is the name of the domain

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To list all the matching sites, enter the following at the command line:

urldb -o all_matching_sites -e reg_exp -d conf-dir

For example:

urldb -o all_matching_sites -e “.*atlas.*” -d server_root/proxy-serverid/config

where

• all_matching_sites lists all the sites that match the regular expression

• reg_exp is the regular expression used

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To list matching urls in a site, enter the following at the command line:

urldb -o matching_urls_from_site -e reg_exp -s site_name -d conf-dir

For example:

urldb -o matching_urls_from_site -e “http://.*atlas.*” -s atlas.phoenix.com 
	-d server_root/proxy-serverid/config

where

• matching_urls_from_site lists all urls from site that match the regular expression

• reg_exp is the regular expression used

• site_name is the name of the site

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To expire or remove matching urls in a site, enter the following at the command line:

urldb -o matching_urls_from_site -e reg_exp -s site_name -x e -d conf-dir
urldb -o matching_urls_from_site -e reg_exp -s site_name -x r -d conf-dir

For example:

urldb -o matching_urls_from_site -e “http://.*atlas.*” -s atlas.phoenix.com 
	-x e -d iserver_root/proxy-serverid/config

where

• matching_urls_from_site lists all urls from site that match the regular expression

• reg_exp is the regular expression used

• site_name is the name of the site

• -x e is the option to expire the matching URLs from the c ache database. This option can not be used with the domain and site modes

• -x r is the option to remove the matching URLs from the cache database

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To list all matching urls , enter the following at the command line:

urldb -o all_matching_urls -e reg_exp -d conf-dir

For example:

urldb -o all_matching_urls -e “.*cgi-bin.*” -d 
	server_root/proxy-serverid/config

where

• all_matching_urls lists all the URLs that match the regular expression

• reg_exp is the regular expression used

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To expire or remove all matching urls , enter the following at the command line:

urldb -o all_matching_urls -e reg_exp -x e -d conf-dir
urldb -o all_matching_urls -e reg_exp -x r -d conf-dir

For example:

urldb -o all_matching_urls -e “.*cgi-bin.*” -x e -d server_root/proxy-serverid/config

where

• all_matching_urls lists all the URLs that match the regular expression

• reg_exp is the regular expression used

• -x e is the option to expire the matching URLs from the cache database

• -x r is the option to remove the matching URLs from the cache database

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config

To expire or remove a list of URLs , enter the following at the command line:

urldb -l url-list -x e -e reg_exp -d conf-dir
urldb -l url-list -x r -e reg_exp -d conf-dir

For example:

urldb -l url.lst -x e -e “.*cgi-bin.*” -d server_root/proxy-serverid/config

where

• url-list is the list of URLs that need to be expired. This option can be used for providing the URL list.

• -x e is the option to expire the matching URLs from the cache database.

• -x r is the option to remove the matching URLs from the cache database.

• reg_exp is the regular expression used

• conf-dir is the configuration directory of the proxy instance. It is located in the following path server_root/proxy-serverid/config.
