Question

WFS reader behind a proxy

To read WFS from a token based secured ArcGis Server we would like to access behind a proxy with http basic authentication to the WFS.

 

I would like to fill the URL like this:

 

https://fmeserver.local.com/MapServer/WFSServer/" target="_blank">https://example.com/proxy.ashx?https://fmeserver.local.com/MapServer/WFSServer/

 

 

When we RUN the translation FME cuts all behind the question mark "?"

 

--> https://example.com/proxy.ashx   (Removed: ?https://fmeserver.local.com/MapServer/WFSServer/)

 

 

How can we avoid this?

 

Is there an "escape" character to avoid this?

 

 

Or another solution?

Hi,

 

 

I'm guessing that the WFS reader has a hard time separating the parameters to the proxy (the outbound URL, in this case) and the necessary parameters that it has to juggle for the WFS features. I would say this is almost to be expected.

 

 

If possible, try to reconfigure your proxy so that you have a specific URL that redirectes, e.g.

 

 

https://example.com/WFSServerProxy.ashx?....

 

 

routes to 

 

 

https://fmeserver.local.com/MapServer/WFSServer?...

 

 

leaving all the parameters unchanged.

 

 

The clue here is to avoid passing the outbound URL as a parameter to your proxy, but rather let the proxy rewrite the URL based on a configuration rule.

 

 

Hope this makes sense :-)

Dear David

 

Thank you for the replay.

 

That would be a solution to reconfigure the proxy. But it is a general proxy for different services, it would be nice not to change this setting. 

 

 

What I suppose is that the reader just attach the parameters after the url?

 

 

On the other hand, is there a direct way to communicate with a secure token WFS from an ArcGIS Server without proxy? Is it possible to use this with a reader from FME?

 

Cheers

 

Sascha
