Case-Insensitive Redirect

<LocationMatch "(?i)^/Site/Website(.*)$">

                RedirectMatch "(?i)^/Site/Virtual(.*)$" http://example.com/Site/Virtual

</LocationMatch>

(?i): how we tell the matching engine to treat the text in a case-insensitive manner.

Apache Case-Insensitive Reverse Proxy

Apache ProxyPass directive is case sensitive, this directive differentiates between example.com/Site and same as example.com/site or any of the 16 different permutations (SitE, sITE, ...)

Regex to the rescue:

ProxyPassMatch "(?i)/Site(.*)$" http://192.168.1.1/Site/$1

(?i): case-insensitive match

(.*): zero or more character

$1: trailing text after match sting in the original string. for example (/site/index.html)

Be careful with the trailing /

View OpenSSL CSR (Certificate Signing Request)

openssl req -text -noout -verify -in CSR.csr

Generate CSR and Key for Apache

openssl req -new -newkey rsa:2048 -nodes -keyout server.key -out server.csr

Remove Passkey from a Private Key

openssl rsa -in private_key_with_pass.key -out private_key_without_pass.key

Convert Apache SSL Private Key to IIS Private Key

To convert private key being used with Apache (usually .key) to IIS private key (.pfx) use the following command:

openssl pkcs12 -export -out private.pfx -inkey private.key -in public.crt

You'll be asked for the password to unlock current private.key (in case it's password protected) and another password to be assigned to the new private.pfx file.

Don't Reverse Proxy a Subdirectory

Assume you have a reversed web server via apache mod_proxy, there might be subdirectories which you don't want to reverse (such as internal Web Services), you can use ! directive like this:

--------------------------------------------------

<VirtualHost *:80>
    ServerName www.example.com

    ProxyPass /webservice !

    ProxyPass / http://10.1.1.100/
    ProxyPassReverse / http://10.1.1.100/
</VirtualHost>
--------------------------------------------------

It's important to have ! directive before the actual ProxyPass direct.
