Igor,
I don't think that is what he wants.
Thomas,
You can use the build in ZnHeaders class from the Zinc HTTP Components
library/framework:
ZnHeaders readFrom: (String crlf join: 'Foo:1
Bar: foo-
bar
Final:true
Foo: another-foo' lines) readStream.
=> a ZnHeaders('Bar'->'foo- bar' 'Final'->'true' 'Foo'->#('1' 'another-foo') )
Note that ZnHeaders>>#readFrom: expects CRLF delimited lines (line the whole of
the internet), while Smalltalk uses CR's, hence the little hack. Your input
will probably use CRLF. Note how ZnHeaders handles identical headers, while it
joins the foo- and bar.
HTH,
Sven
