mod_rewrite multiple question marks

Question

Occasionally the marketing department would send out a mailer that contains links with multiple question marks in them.

http://www.acme.com/site-page.jsp?content=mainpage?utm_campaign=somecampaign&utm_source=email

This results in the application server interpreting the mainpage?utm_campaign as the parameter instead of just mainpage. Is there a way to intercept these erroneous urls in Apache and replace the second ? with an &.

Answer 1

You can put this code in your htaccess (which has to be in root folder)

RewriteEngine On

RewriteCond %{QUERY_STRING} ^(.+?)\?(.+)$
RewriteRule ^site-page\.jsp$ /site-page.jsp?%1&%2 [R=302,L]

This code will redirect

/site-page.jsp?content=mainpage?utm_campaign=somecampaign&utm_source=email

to

/site-page.jsp?content=mainpage&utm_campaign=somecampaign&utm_source=email

Now you have those params:

• content = mainpage
• utm_campaign = somecampaign
• utm_source = email

Note: feel free to change 302 (temporary) redirect to a 301 (permanent) redirect

EDIT

RewriteCond %{QUERY_STRING} ^(.+?)\?(.+)$
RewriteRule ^(.*)$ /$1?%1&%2 [R=302,L]
