Sending Status Messages indian14311-Jan-11 7:46 indian143 11-Jan-11 7:46  Hi All, I have a ASP.Net Web Application which sends status messages to another JSP or some other web application throgh a WCF service hosted in my IIS 7.0. Normally it is sending the messages. But some times it may fail, so I want to re-send the failed status messages. So can anybody help me which approach is the best fit for this requirement? I am confused about the approach, like whether should I use a database table to keep the failed records and activate it through the Windows service? Or should I put the failed records in XML or Log files and read it from there resend it? Is there any other effient way than implementing Windows service? Which is the best one please help me in finding the good option, for performance of the application and implementation? Thanks & Regards, Md.

If you want to build your own, you could implement it as a database message queue and have a separate process handle the delivery of the messages. You have all kinds of flexibility (and complexity) by implemeting it as a database table, but it is really up to you to decide how to implement it.

Create a token based on session id and time in the Global Session Start method. 2. Store token in hidden form variable on every page load. 3. On submission, compare form variable with session token. Question: What is the proper way to implement my solution? This has to be wrong. I can not see in anyway how this would prevent CSS. Under no circumstances would the form variable differ from the session variable. Re: Proper Procedures to Prevent Cross Site Scripting.
