[users@httpd] Rewrite query string?
Hi,
I'm trying to replace "searchword" with just "search" in the following URL:
https://example.com/search?searchword=CVE-2021-4014&Search=
I've tried the following RewriteCond/RewriteRule in various forms, but
not sure what I'm doing wrong.
RewriteCond %{QUERY_STRING} ^searchword=(.*)
RewriteRule ^ q=$1 [NC,L]
Ideas for what I'm doing wrong would be greatly appreciated.
Thanks,
Dave

probably should restrict to /search as edited

Same thing applies for .*$ - leave it out.

You don't want to use ^.* - just use the substring match behaviour by
removing ^.* if you want to match searchword anywhere in the value.

Whoops, meant to add a comma in the capturing group. Also the end is
ambiguous. Maybe
searchword=(\w{1,})
Should match all the way to the end of the query value (& is not in \w), or
the end the query string if it’s the last parameter.

You can append the 'R' flag if you need it to redirect. Otherwise,
just the internal representation is changed.
RewriteRule ^ %{REQUEST_URI}?search=%1 [NC,L,R]

This didn't work :-( It found a match, but it doesn't appear to have
performed the replacement:
Thu Jan 04 16:41:41.144300 2024] [rewrite:trace4] [pid 510782:tid
510817] mod_rewrite.c(493): [client 68.195.111.42:0] 68.195.111.42 - -
[webstage.example.com/sid#55795fe93698][rid#7fa7140322c0/initial]
RewriteCond: input='searchword=CVE-2021-4014&Search='
pattern='^searchword=([^&]+)' => matched
It even shows the rewrite:
[Thu Jan 04 16:41:41.144316 2024] [rewrite:trace2] [pid 510782:tid
510817] mod_rewrite.c(493): [client 68.195.111.42:0] 68.195.111.42 - -
[webstage.example.com/sid#55795fe93698][rid#7fa7140322c0/initial]
rewrite '/search' -> '/search?search=CVE-2021-4014'
However, this change is not reflected in the Location bar in my browser.
Maybe I'm missing something? Is there any way to enable logging only for
the RewriteRule/RewriteCond I'm currently working with, or to otherwise
be able to more specifically identify the rule I'm testing?
I'm using:
LogLevel info rewrite:trace5
Thanks,
Dave

I think something like this is closer:
RewriteCond %{QUERY_STRING} ^searchword=([^&]+)
RewriteRule ^ %{REQUEST_URI}?search=%1 [NC,L]
- In the cond, I am dropping everything in the query after the CVE
value, since Search= and search= would be confusing together.
- The substitution needs to be the full URL -- using the
%{REQUEST_URI} variable here
- Using a ? in the substitution will replace the existing query
- %1 is the first capture in the preceding condition

Captured values via a RewriteCond are referenced with %1 and not $1.
Either way, I recommend using the rewrite log to see what is actually happening.
