WCF REST hosted inside ASP.NET WebForms app - 400 on production server
-
Sticky problem with a few WCF REST services on a production machine. All the services are fine across other servers, failing any interactions on one particular server with a 400 Error. We have a couple of REST services contained in our basic webforms application. We're calling these via POST method from javascript (raw js, no jQuery). These services then use a standard service reference to call down to "real" WCF services (not restful). All seems fine on several dev machines and several other live sites, but for one of our sites, all we get out of the REST side of things are 400 (Bad Request) errors. We've tried various things: Dropped a "Really simple rest" service onto the same server, call in the same way and works fine - so don't think it's a server issue. Checked IIS config for things like wildcard maps etc - all seems to be the same as other servers. Written a quick Powershell script to call - this also fails with a 400, so we think our JS side of things is OK. Checked request format etc (JSON) in Fiddler - seems to be fine and the same as works on other servers. Tried to create a new instance of our complete app on the same server - same problem, so it looks like it's something specific to our server side code in this app only, except the server side code is the same as the really simple service above - with one exception - we use code to create our binding object and endpoint rather than having them in web.config. The settings we use are however the same as per the standard info added when adding the normal service reference. We're about running out of ideas on this one, so any pointers as to areas to look at would be greatly appreciated.
