Dear Wiki user, You have subscribed to a wiki page or wiki category on "Nutch Wiki" for change notification.
The following page has been changed by susam: http://wiki.apache.org/nutch/HttpAuthenticationSchemes The comment on the change is: typo fixes ------------------------------------------------------------------------------ Even though, the 'http.auth.host' property is required only for NTLM authentication, it is advisable to set this for all cases, because, in case the crawler comes across a server which requires NTLM authentication (which you might not have anticipated), the crawler can still fetch the page. == Authentication Scope Specific Credentials == - This is an advanced feature that lets the user specify different credentials for different authentication scopes. After that you might want to try this out and appreciate the advantages. + This is an advanced feature that lets the user specify different credentials for different authentication scopes. === Quick Guide === An example of 'conf/httpclient-auth.xml' configuration is provided below: @@ -96, +96 @@ If a page, say, 'http://192.168.101.34/index.jsp' requires authentication, then the common credentials would be used since there is no credential defined for this scope. - The 'realm' attribute is optional in <authscope> tag and it can be omitted if you want the credentials to be used for all realms on a particular web-server (or all remaining realms as shown in the Quick Guide section above). One authentication scope should not be defined twice as different <authscope> tags for different <credentials> tag. However, if this is done by mistake, The credentials for the last defined <authscope> tag would be used. This is because, the XML parsing code, reads the file from top to bottom and sets the credentials for authentication-scopes. If the same authentication scope is encountered once again, it will be overwritten with the new credentials. However, one should not rely on this behavior as this might change with further developments. + The 'realm' attribute is optional in <authscope> tag and it can be omitted if you want the credentials to be used for all realms on a particular web-server (or all remaining realms as shown in the Quick Guide section above).
