Long press the settings button, check the option "custom file handling" to enable the functionality.
The custom file handling configuration file is "/sdcard/uweb/default.filecap", each line of it has the format as follows:
[file extension]:[mimetype]:[command line]
The "[file extension]" part can have at most two-segment of extensions such as "txt.xz","html.gz".
"[mimetype]" indicates the type of "[command line]" output.
"[command line]" is same as the one in default.cmds. The most often used replacements are:
%u (url), %U (urlencoded url), %c (cookie), %p (site password, curl format).
