Setting “KeepAlive” Value in BizTalk Web Service Calls

A few months back I posted about getting “canceled web requests” when calling a service on WebLogic from a BizTalk Server. Now, there appears to be a Microsoft hotfix that can address this.

While looking for another hotfix, I located this …

• Messages may be suspended when you use the HTTP adapter to send multiple messages to an Apache Web server, and the following error message may occur in BizTalk Server 2006: “Underlying connection was closed”

The cause given states “This problem occurs because you cannot set the HTTP header KeepAlive property to false when you use the HTTP adapter to send a message.”

There’s a non-hotfix workaround offered (which isn’t great), and then a description on how to set the “KeepAlive” to “false” after applying the hotfix. It’s a bit humorous, however, that the installation instructions include this little tidbit … “We do not recommend that you deploy this schema because future BizTalk Server updates may include an HTTP schema to set the KeepAlive property.” I’d prefer you not offer it as an option then! It’s recommended that you do NOT actually build out the property schema, but instead set the KeepAlive value in the pipeline.

Setting KeepAlive to false isn’t a great thing to do, but if you’re desperate, you now have a means to do it.
