Hey Stanislas,

 

i like to comment your provided snippets...

 

1st snippet:

 

[HTTP::path] and [HTTP::query] seems to perform an ordinary [getfield [HTTP::uri] "?" (1|2)] in the background. In the end your snippet is splitting [HTTP::uri] two times followed by a substitution to produce a string comparable with [HTTP::uri] but seperated by a "&" sign (i dont understand the "&" sign at all, since the URL seperator between PATH and QUERY is always the "?" letter).

 

Then you use a [string map] on the substituted string to change the leading part. Well, [string map] is a very powerfull command to scan and replace (one or many) contents somewhere within string. But if the content to be replaced is at the beginning then [string range] in combination with subtitution does performance wise a somewhat better job.

 

2nd snippet:

 

Contains also a "&" sign as seperator between PATH and QUERY. See discription above.

 

Cheers, Kai
