Contact forms, Caches and CDN

Hello all –

I am trying to find a suitable contact forms plug in. Should be simple! But we are having problems with many of them due to the fact that we are using caching and a CDN. This seems to cause them to periodically fail. Of course we can exclude the ‘contact us’ page from the cache – but some customers want a ‘Quick Contact’ form or similar at the bottom of each page (for example). Excluding every page from the cache/CDN would be ridiculous, surely?

So can anyone suggest a forms plug in that can have customisable fields, where the completed message goes to a normal mailbox (rather than into the database to be accessed from the WP back end), works with caching/CDN & allows the option to direct the user (on successfully sending a message via the form) to a new landing page?

It doesn’t seem like something that only we are trying to do!

Many thanks – Jon Hall
