Using logical operators in lighttpd.conf

Question

I have two sub-domains which I want to redirect to the same directory:

$HTTP["host"] =~ "sub1\.example\.com$" {
    server.document-root = "/home/adam/html/sub_domain" 
}

$HTTP["host"] =~ "sub2\.example\.com$" {
    server.document-root = "/home/adam/html/sub_domain" 
}

Naturally, I've tried:

$HTTP["host"] =~ "sub1\.example\.com$" OR $HTTP["host"] =~ "sub2\.example\.com$"{
    server.document-root = "/home/adam/html/sub_domain" 
}

But got:

2011-03-14 10:19:30: (configfile.c.855) source: /etc/lighttpd/lighttpd.conf 
    line: 199 pos: 36 parser failed somehow near here: or

This failed with OR (upper case), or and even c-style ||.

Any idea how to avoid the awkward code repetition?

This question is a copy of an unanswered post I've published in the lighttpd forum.

Why not just...?

$HTTP["host"] =~ "^sub(1|2)\.example\.com$" {
    server.document-root = "/home/adam/html/sub_domain" 
}

Note: This method does not work with `$SERVER["socket"]`. – starbeamrainbowlabs Apr 30 '15 at 14:16

Alicia's answer is probably the best for this question, but if someone stumbles upon this for whom a regex fix doesn't work – like I did before – I want to quickly share which solution worked for me:

Lighttpd has no AND / OR logical operators, but it's possible to obtain the same behavior by nesting / chaining conditions.

Logical AND:
condition1 {
    condition2 {
        doSomething
    }
}
→ nested if blocks are equivalent to a logical AND

Logical OR:
condition1 {
    doSomething
}
condition2 {
    doSomething
}
→ chained if blocks are equivalent to a logical OR

if-then-elif-else construct:
condition1 {
    doSomething1  ← then block
}
else condition2 {
    doSomething2  ← else if block
}
else {
    doSomething3  ← else block
}

Taken from: https://doc.callmematthi.eu/lighttpd.html

I'd add an `else` in the "logical OR" case too, else if both conditions are true it would "do something" twice. — lapo, Sep 06 '22 at 20:18

Try -o for logical OR. Try -a for logical AND.

Also reference this page for some more operator commands in *nix.

report back and let us know if that works!

Does not work: `2011-03-14 14:04:05: (configfile.c.855) source: lighttpd.conf line: 200 pos: 36 parser failed somehow near here: -o` – Adam Matan Mar 14 '11 at 14:04
