| Summary | 0005660: Varnish Cache default config.vcl removes parameters from URL but not the ROBOTS tag from the sourecode | ||||
| Description | If something calls the Shop with an GET request and it has parameters added to the url, the shop will always print "<meta name="ROBOTS" content="NOINDEX, FOLLOW">" in the sourecode. Our standard varnish configuration will remove some parameters from the URL, but not this ROBOTS tag from the sourcecode. Under circumstances the page, containing this tag, will be cached and always delivered. For example: Google calls the shop with parameters and the Varnish put this site - with the tag - into the cache folder. Google calls later the shop again and get, for example on the startpage, the ROBOTS tag to not index it. | ||||
| Steps To Reproduce | 1. Call http://demoshop.oxid-esales.com/professional-edition/ 2. Have a look into the sourcecode and search after "<meta name="ROBOTS" content="NOINDEX, FOLLOW">". You will not find it. 3. Call http://demoshop.oxid-esales.com/professional-edition/?foo=bar 4. Have a look into the sourcecode and search after "<meta name="ROBOTS" content="NOINDEX, FOLLOW">". You will find it. So there is a chance that Varnish will cache this page and all search engines are rejected. | ||||

This is probably related to the behaviour of oxUBase::noIndex(). |
|
|
This will not happen for random parameters like ?foobar=1 It's just those parameters, defined in the varnish vcl, like gclid, utm_source, etc. |
|
|
eShop prints "<meta name="ROBOTS" content="NOINDEX, FOLLOW">" because of search engine, which should not crawl same page with 2 different URLs for example http://demoshop.oxid-esales.com/professional-edition and http://demoshop.oxid-esales.com/professional-edition/?foo=bar . Pages with URLs(for example start page) which have parameters like gclid, utm_source, etc. were cached to the same page as start page without parameters. In this case we could have a problem, cache entry might have wrong content. To solve it we separated cache from one cache entry to two cache entries: start page without parameters and start page with parameter campaign=1. |
