SOAPClient function unable to parse HTTP transport compressed response from SOAP service

[rsarvas]

This is more of an issue with jQuery.ajax than with your code, but I noticed on large XML responses sent from my services HTTP transport compression started to kick in and previously working SOAP requests started to cause JavaScript errors due to the "xhr" var not being defined correctly, causing parts of the "xhr.always" function to fail. I've attempted to modify the "Accept-Encoding" in both the jQuery ajax "headers" and "beforeSend" sections, but the value appears to either be read only or overridden by the browser on send.

Partial packet sniffer example output below:

Disabling HTTP transport compression on the SOAP server resolves the issue.
