I think I now have a work-round to the HTML mangling (XML parsing error) problem caused by Wind's WAP Proxy. It uses
privoxy and seems to work on both my laptop and the Nokia N810 tablet - though I cannot test it with Wind's proxy from here in the UK. It changes the http 'content type' header to text/html which (in Firefox at least) stops the browser trying to parse as XML.
The relevant configuration lines are:
In config:
# Wind's proxy server
forward / 192.168.200.10:9401
In user.action:
# Change content type on all sites to html
{+server-header-filter{xml-to-html}}
/
Install, run, and set up privoxy as in its documentation.
Feedback from anyone in Greece using Wind + Non-Stop welcome. I've only tried it with Mozilla-based browsers.
