This commit implements the following new actions :
- "set-method" rewrites the request method with the result of the
evaluation of format string <fmt>. There should be very few valid reasons
for having to do so as this is more likely to break something than to fix
it.
- "set-path" rewrites the request path with the result of the evaluation of
format string <fmt>. The query string, if any, is left intact. If a
scheme and authority is found before the path, they are left intact as
well. If the request doesn't have a path ("*"), this one is replaced with
the format. This can be used to prepend a directory component in front of
a path for example. See also "set-query" and "set-uri".
Example :
# prepend the host name before the path
http-request set-path /%[hdr(host)]%[path]
- "set-query" rewrites the request's query string which appears after the
first question mark ("?") with the result of the evaluation of format
string <fmt>. The part prior to the question mark is left intact. If the
request doesn't contain a question mark and the new value is not empty,
then one is added at the end of the URI, followed by the new value. If
a question mark was present, it will never be removed even if the value
is empty. This can be used to add or remove parameters from the query
string. See also "set-query" and "set-uri".
Example :
# replace "%3D" with "=" in the query string
http-request set-query %[query,regsub(%3D,=,g)]
- "set-uri" rewrites the request URI with the result of the evaluation of
format string <fmt>. The scheme, authority, path and query string are all
replaced at once. This can be used to rewrite hosts in front of proxies,
or to perform complex modifications to the URI such as moving parts
between the path and the query string. See also "set-path" and
"set-query".
All of them are handled by the same parser and the same exec function,
which is why they're merged all together. For once, instead of adding
even more entries to the huge switch/case, we used the new facility to
register action keywords. A number of the existing ones should probably
move there as well.
