Services_Settings
This section provides an overview of the Services > Settings page and a description of the configuration tasks available on this page.
The Services > Settings page allows the administrator to configure various settings related to HTTP/HTTPS, Citrix, Global Portal character sets, and one-time passwords.
Administrators can take the following steps to configure HTTP/HTTPS Service Settings:
1. The Enable Content Caching check box is selected by default. Administrators may disable the check box if they choose to do so. However, changing the Enable Content Cache setting will restart SRA Services, including the web server.
In the Cache Size field, define the size of the desired content cache. 5 MB is the default setting, but administrators may set any size in the valid range from two to 20 MB. Select the Flush button to flush the content cache.
2. Check the Enable Custom HTTP/HTTPS Response Buffer Size check box, if you wish to establish a response buffer. Enabling this check box. Set the desired buffer size using the Buffer size drop-down menu. This limit is enforced for HTTP and HTTPS responses from the backend Web server for plain text, Flash, and Java applets. The default size of the buffer is 1024 KB.
3. Check the Insert Proxy Request Headers check box to insert these types of headers into the HTTP/HTTPS requests to the backend Web server. The following headers will be inserted:
• X-Forwarded-For: Specifies the client IP address of the original HTTP/HTTPS request.
• X-Forwarded-Host: Specifies the “Host” in the HTTP/HTTPS request from the client.
• X-Forwarded-Server: Specifies the host name of the SRA proxy server.
4. Check the Enable Flash Rewriting check box to rewrite URLs contained in Flash files. Rewriting URLs in Flash may work only with a few websites. Application Offloading is recommended for unsupported Web sites. This feature is disabled by default.
The administrator needs to host the Citrix clients on a local Web server and have the SRA download these clients from there. For example, place the following Citrix Receiver clients on the Web server:
• For ActiveX: Receiver for Windows 3.0 – CitrixReceiver.exe
• For Java: Receiver for Java 10.1 – JICAComponents.zip
Perform the following steps to configure Citrix Service Settings:
1. The Dell SonicWALL SRA appliance will always perform the Citirix client detection when using Citrix Bookmarks. Click the Disable client detection by Citrix server check box to disable this feature wen using Citrix Bookmarks. Note that this feature is compatible with Citrix XenAPP 5.0 or later.
2. Select the Enable custom URL for Citrix Java client downloads check box to use your own HTTP URL to download the Citrix Java client. Fill-in the custom URL in the URL field. If this option is not enabled, the default URL will be used.
3. Select the Enable custom URL for Citrix ActiveX client downloads check box to use your own HTTP URL to download the Citrix ActiveX client. Fill-in the custom URL in the URL field. If this option is not enabled, the default URL will be used.
1. Use the Default Character Set drop-down menu to set the language compatibility character set to be used with standard and non-standard FTP servers. The character set only applies to FTP sessions and bookmarks. Standard encoding (UTF-8), the default setting, should work for most FTP servers.
The One Time Password Settings section allows administrators to configure settings relating to the creation and communication of one-time passwords. One-time passwords are dynamically generated strings of characters, numbers or a combination of both. For compatibility with mail services that allow a limited number of characters in the email subject (such as SMS), the administrator can customize the email subject to either include or exclude the one-time password. The email message body can also be configured in the same way. The administrator can also select the format (such as characters and numbers) for the password.
To configure the One Time Password email subject format, email body format, and change the default character types used when generating one time passwords, perform the following tasks:
1. In the Email Subject field, type the desired text for the one-time password email subject. The default subject consists of OTP plus the actual one-time password (represented here with the parameter placeholder %OneTimePassword%).
2. In the Email Body field, type the desired text for the one-time password email message body. The default message is simply the one-time password itself (represented here as %OneTimePassword%).
Variables can be used in the subject or body of a one-time password email:
• %OneTimePassword% - The user’s one-time password. This should appear at least once in either the email subject or body.
• %AD:mobile% - The user’s mobile phone as configured in Active Directory (AD).
• %AD:________% - Any other Active Directory (AD) user attribute. See the Microsoft documentation link below the Email Body field for additional attributes.
3. In the One Time Password Format drop-down list, select one of the following three options:
• Characters – Only alphabetic characters will be used when generating the one-time password.
• Characters and Numbers – Alphabetic characters and numbers will be used when generating the one-time password.
• Numbers – Only numbers will be used when generating the one-time password.
4. Use the One Time Password Length fields to adjust the range of characters allowed for one-time passwords.
5. Click the Accept button in the upper right corner of the Services > Settings page to save your changes.
