Hello, I am in need of some help.

My project is HTTP Server application.
After updating to Lazarus 1.8.0 (fpc 3.0.4) I have began to experience
some strange behavior.
When for example after sending the first request to my application I
get a response without error.
But after I have sent the same request a 2nd time I get an error with
a message  " Duplicate name: A component named "FPMobile" already
exists ".

I have tried to create a new HTTP Server application with one module
and one action that returns simple text and I still get the same error
after 2nd request.
I didn't and still don't have this issue with Lazarus 1.6.4 fpc 3.0.2.

Thank you all!

In a similar message on the mailing list, M VanCanneyt wrote that you
should set the TCustomHTTPModule descendant's Kind property to
wkOneShot, so you could try that.

Just to be sure.
Did you set
Application.LegacyRouting:= True
So the application doesnot use the new routing system and handles the
modules in the old fashioned way

Oh, my.

Thank you very much for that note nummer8.

I still use legacy compiler/units for production and seem to have
missed that completely . More information here.

Just for completeness sake: this is now fixed in trunk. See this bug
report of mine as I had encountered the same problem.
