form_key

[will-parsons]

Unfortunately, the addition of form_key in Magento Community 1.8 will break 'add to cart' functionality when cached in Varnish.

Workarounds I've seen just seem to disable / bypass the form_keys entirely:

https://github.com/deivisonarthur/Inovarti_FixAddToCartMage18 https://bitbucket.org/supportdesk_nl/turpertine-formkey-workaround/src

Are there any plans to implement something similar?

Thanks!

i second this. On my website when I enabled this module i can see a lot of <esi:include src= tag because ESI is not supported in community version of PageCache. They are not replaced by correct form key. If it is not supported, can you suggest how to disable ESI tag so I can apply other fix to it?

[PHOENIX-MEDIA]

We pushed a new release on Github that now supports form_keys. However you have to update your VCLs according to the README_VARNISH_CACHE.txt. Furthermore you need to adjust your Varnish startup parameters and add "-p esi_syntax=0x03" in order to parse the ESI tags properly.

Please note that ESI in the Github version is only supported to resolve the form_key issue. If you are looking for ESI support in other Magento blocks like the shopping cart please have a look at out PageCache powered by Varnish Enterprise version on Magento Connect.

Thanks for responding. I already downloaded your newest realease of Pagecache module several days ago. I added -p esi_syntax=0x03 in startup parameters. What i don't understand is "update your VCLs". I used these ones:

• default_3.0.vcl
• vars.vcl but it doesn't work so I assume i need this file esi_3.0.vcl ? it doesn't come with PageCache community version. That's why i want to asked

I am having an issue with this. The changes work but the form key is not being included. The request works:

Request Method:GET
Status Code:760 lAprIeHezAj4M0q9

But the output is always empty:

<input name="form_key" type="hidden" value="" />

[PHOENIX-MEDIA]

Have you added "-p esi_syntax=0x03" as Varnish startup parameter?

[gibbs]

Hi. Yes - it looks like this:

DAEMON_OPTS="-a ${VARNISH_LISTEN_ADDRESS}:${VARNISH_LISTEN_PORT} \
             -f ${VARNISH_VCL_CONF} \
             -T ${VARNISH_ADMIN_LISTEN_ADDRESS}:${VARNISH_ADMIN_LISTEN_PORT} \
             -t ${VARNISH_TTL} \
             -S ${VARNISH_SECRET_FILE} \
             -s ${VARNISH_STORAGE} \
             -p esi_syntax=0x03 \
             -p shm_reclen=4096 \
             -w ${VARNISH_MIN_THREADS},${VARNISH_MAX_THREADS},${VARNISH_THREAD_TIMEOUT}"

Otherwise the ESI markup should be returned.

This is strange. Please post a URL where we can check it or write an email to support@phoenix-media.eu. Thanks.

Here's an example on a development domain with full headers being returned and multiple forms: http://cc.gcmdev.co.uk/head-gear/nrs-havoc-helmet

Compare the output here: http://magento.phoenix-media.eu/varnishcache/getformkey/

Seems smth is wrong with your VCL setup or Varnish.

Hi,

Will updating the vcl break magento stores running with old module versions?

Thanks, Gabriel

[PHOENIX-MEDIA]

No, the changes are backwards compatible.
