Hi All,

how do you transfer data between two web applications?

For simple (non-security sensitive) data I would think QueryString would do.

The question is a bit vague, but you could use an intermediate like a Database to store the information.  Then each site queries the database independently to get the 'shared' information.  This might be the best solution if the sites are hosted on different servers.  If a Database is not available, another option you could consider the intermediate to be a service exposed which both sites can see as well.

Another consideration would be to use 'Application' level variables.  These variables can hold information available to all web sites running on the same server. 

Lastly, the QueryString is an option, but is has limitations and nothing passed should be sensitive in nature.

What about a web service to put data on the db ? another web service to get the data?

Sure, but you don't need (2) web services for that.  Just use the same service, but different exposed methods for different purposes.

I use Caspio. It's a fast and easy way to build web forms and apps without coding. You can create apps to collect and share data within a hosted database. http://www.caspio.com/web-database-platform/?s=282

If you wanted to go simpler than that, you could use POST and GET commands for the communication, I had a project whereby I had to POST values to a secure transaction system, which worked nicely from an interoperability point of view.

 

However to summarise the suggestions:

• POST/GET.
• Webservices.
• Centralised (shared) database.
• RSS feed.

Yes querystring too, but if your looking for a security safety / good architecture approach, you should really stick to the more server-side methods - just a personal view.
