meaning of "]+" in the documentation

hey,

 

what is the meaning of the sign "]+" for example in the documentation of the http:respond function HTTP::respond [-version [1.0|1.1|auto] ] [content ] [noserver] [

 

]+ i know i can send multiple tupples of but what i mean is can i send a "list" or a "string" with this structure somhow? string like "key value key value" wont be added to the http headers. if i used the split function on this string it also didnt returned those http headers.

 

can someone help?

 

what i need is to rewrite http response from 302 to 301, and i have couple of headers that might be in the original respond in which i need to copy to the new response.

 

thanks
