The only other functionality beside CFQUERY available to SAS is the CFHTTP functionality found in ColdFusion, but a Flash movie is very limited as to what it can do with the results of a CFHTTP call. The main reason why you would want to use SSAS s HTTP functionality is to POST data to an external server. Listing 27-3, for example, shows how you would POST to an external server and send its response data back to the Flash movie.Related: Intelligent Mail Generation .NET

In those situations it is wise to combine LIMITED ACCESS (312) with the checks close to the functionality, as proposed y FULL ACCESS WITH ERRORS (305).

These application servers can be placed on a more protected network than the Web servers. This protected network will have easier (possibly direct) access to the corporate information and services required by the Web-based application. The external router should be configured to deny any attempted access to any network addresses outside of those known in the DMZ. To increase security, any requests with a destination address that does not match the Web server address (or that of the Web server cluster) may be rejected. The external router may also reject requests based on the port number of the request, for example rejecting any request that is not for port 80. The external router will therefore block direct attacks on the internal router, and possibly the firewall. The Web servers will be built solely for the purpose of delivering static Web content or proxying requests through to the application servers. These Web servers should be locked down (or hardened ) by removing unnecessary functionality. Such hardening helps to prevent other, unintended, access to the servers. The internal router will limit network traffic to connections between the Web servers on the DMZ and specific internal servers, such as the application servers, using a fixed set of protocols. This restriction reduces the risk of attack on other internal systems. The use of an internal router helps to reduce the risk of attack should the external router be breached. Because of this threat, no traffic should be allowed directly from the external router to the internal router.Related:

As you would expect, in the Closing event handler, we simply call SaveIfDirty and then set the Cancel property of CancelEventArgs to the return value of the SaveIfDirty method Next, let s look at the code that will prompt the user to save (Listing 183) This code snippet contains two methods SaveIfDirty and SaveForm The SaveIfDirty method is very simple First, we check to ensure that there is a form loaded If there isn t, formControl1XmlForm will be null (Remember from Table 182 that the XmlForm property gives you access to the InfoPath object model) If a form is loaded, we then check to see hether the user has entered data by querying the Dirty property If the form is dirty, we then ask if the user would like to save the form If he or she chooses Yes, we call the SaveForm method If he or she chooses Cancel, we return false to indicate that the form shouldn t be closed If the user chooses No, we simply return true, which will cause the form (or the application) to close without saving the data.
