Thanks for the example Alexandr.
I know it seems like sometimes the re-factorings can lead to errors, but in the long run it means the code gets simpler. There are just the odd edge case that needs to be handled sometimes.
you can make the fix in your own netweb.clw if you like.
search for the NetWebServerWorker.SetOption method.
change the line
st.split(',','(|{{|[',')|}|]',false,,,'|',st:nested)
to
st.split(',','(|{{|[|"',')|}|]|"',false,,,'|',st:nested)
it'll obviously be fixed in the 7.12 build as well.
Cheers
Bruce
