Using Caché Server Pages with a Remote Web Server Restart IIS to apply the changes. 3.1.4.2 Add Aliases to Apache Configurations If you are using an Apache Web server to control a remote Caché server and your application path is altered from the /csp default, you must manually add a corresponding alias to the Apache configuration file pointing to the local CSP directory. For example, to remotely serve the CSP applications on the Caché instance MyCache on Machine C from the application path defined on the Web server, /myapp/csp, add the following alias line to the httpd.conf file on Machine W: Alias /myapp/csp "C:/MyCache/CSP" Restart the Apache Web server to apply the changes. 3.2 Accessing CSP on Multiple Caché Servers The need to configure a single Web server to access the same CSP application on a number of different Caché servers often arises with the Systems Management Portal. This is particularly true of OpenVMS-based Caché installations in which clustered environments contain many instances of Caché. You may also use a single Web server to access several different applications on various remote Caché servers. There are several different ways to configure your system to accomplish this. This section uses the System Management Portal as the example application; however, you can apply the same procedures to any CSP application that is distributed over multiple Caché instances. The portal application is usually called via: http://domain.com/csp/sys/UtilHome.csp To access this same application on multiple servers is to factor a name representing the individual Caché servers into the application path. For example: http://domain.com/cache1/csp/sys/UtilHome.csp http://domain.com/cache2/csp/sys/UtilHome.csp Where cache1 and cache2 effectively represent separate instances of Caché. You can configure this using the CSP Gateway Management application as follows: 1. Access the configuration application as shown: http://localhost/csp/bin/Systems/Module.cxw 54 CSP Gateway Configuration Guide
Configuring Apache Virtual Hosts 2. Click Server Access to create a server configuration for cache1 and cache2. 3. Click Application Access to create the application paths /cache1/csp/sys/ and /cache2/csp/sys/. Set the Default Server for path /cache1/csp/sys/ to be the name of the server configuration set up for cache1 in the previous step. Set the Default Server for path /cache2/csp/sys/ to be the name of the server configuration set up for cache2 in the previous step. 4. Within the configuration for the two remote Caché servers, cache1 and cache2, ensure that the paths to the portal are defined as paths /cache1/csp/sys/ and /cache2/csp/sys/ respectively. 5. If the Web server is IIS then set up virtual directories for /cache1 and /cache2 as described in the Add Virtual Directories to IIS section. If using an Apache Web server see Add Aliases to Apache Configurations. 3.3 Configuring Apache Virtual Hosts An alternative method for accessing an application on multiple servers is to use virtual host arrangements. Virtual hosts are a common feature in Apache Web server configurations and are straightforward to set up in this server environment. For example, consider two virtual hosts, each listening on a separate TCP port: http://virtual_host1:81/csp/sys/UtilHome.csp http://virtual_host2:82/csp/sys/UtilHome.csp Both virtual_host1 and virtual_host2 are served by the same Web server and CSP Gateway. The following shows the Apache configuration (httpd.conf) for this arrangement: ServerName virtual_host1 ServerName virtual_host2 Configure the use of these virtual hosts using the CSP Gateway Management application as follows: 1. Navigate to the Caché Server Pages Gateway Management home page by pointing a browser to: http://localhost/csp/bin/Systems/Module.cxw 2. Click Server Access to create a server configuration for cache1 and cache2. 3. Click Application Access to create the application paths //virtual_host1/csp/sys/ and //virtual_host2/csp/sys/. Note the use of the double forward-slash (//) to introduce the virtual host name. Set the Default Server for path //virtual_host1/csp/sys/ to be the name of the server configuration set up for cache1 in the previous step. Set the Default Server for path //virtual_host2/csp/sys/ to be the name of the server configuration set up for cache2 in the previous step. 4. No changes are required in the configuration of the two remote Caché servers. The application path for the portal remains as /csp/sys/ in both cases. See Virtual Hosts Overview for more information.
