Hum, right, but the webserver SHOULD accept the 
request, ad the '!' character is neither a delimiter, 
nor an "unwise" character.

Anyway, I will change the CHAR_XXAVOID macro in 
htslib.c, line 393, st that the '!' character can be 
encoded:

#define CHAR_XXAVOID(c)   ( strchr(" *'\"",(unsigned 
char)(c)) != 0 )
by
#define CHAR_XXAVOID(c)   ( strchr(" *'\"!",(unsigned 
char)(c)) != 0 )
