Confusion is especially strong because the documentation for the ;TI"Nescape function includes a reference to the URI specifications. ECMA-262 ;TI"Lescape is not however a URI escape function, it is a javascript escape ;TI"Tfunction, and is not fully compatible. Most notably, for characters outside of ;TI"Dthe BMP. Users should use the more correct encodeURI functions.;T@ S; ; i;I"+Known issues with Rack and Web servers;T@ o; ;;;[o;;0;[o;;[I"ELighttpd sets wrong SCRIPT_NAME and PATH_INFO if you mount your ;TI"EFastCGI app at "/".

The current ;TI"P parameter parsers in Rack are based on a combination of the HTTP and CGI ;TI"S specs, and are intended to round-trip encoding and decoding. There are some ;TI"A choices that may be viewed as deficiencies, specifically: ;TI"U - Rack does not create implicit arrays for multiple instances of a parameter ;TI"5 - Rack returns nil when a value is not given ;TI"> - Rack does not support multi-type keys in parameters ;TI"R These issues or choices, will not be fixed before 2.0, if at all. They are ;TI"R very major breaking changes. Users are free to write alternative parameter ;TI"Q parsers, and their own Request and Response wrappers. Moreover, users are ;TI" encouraged to do so.;T;0: @file@:0@omit_headings_from_table_of_contents_below0
