ChEMBL Cookies
On the 26th May 2011 new European regulations will come into force, which are aimed at providing website users with a better understanding of data being collected when they visit a website. Covered under these regulations, is the use of cookies, which are small pieces of of text set by some websites and can be used for authentication, saving site preferences/shopping cart selections and storing session information. In short, the cookie is being used to get around the inherently stateless nature of HTTP.There is currently a bit of confusion over what the final regulations and national implementations will be, so the Information Commissioner’s Office (ICO) has drawn up some guidelines, however these will not be finalised until after 26th May 2011 :(. In preparation for these changes we thought we would list the cookies which might be set when a user visits the the ChEMBL interface:
| Cookie Name | Details |
|---|---|
| ci_session | Generated by Codeignitor web application framework and used to store session information for each user |
| chembl_sketcher | Stores user selected compound sketcher on https://www.ebi.ac.uk/chembldb/index.php/compound page |
| marvin, jme, jdraw | Stores sketched structure on https://www.ebi.ac.uk/chembldb/index.php/compound page. Cookie is used for each sketcher as different formats are used to store structure. |
| __utma, __utmb, __utmc, __utmz, __utmv, __utmx | Cookies set by Google Analytics code, more details can be found here |
Most modern browsers offer the ability to block the receipt and storage of cookies.
