iShare now uses Local Storage rather than Cookies to store user state information e.g. layers selected, position on map) etc. This should have no visible effects to the user other than that they should no longer hit problems when using large numbers of layers. Note: Currently there is no expiry date on localStorage settings as there is for cookies. |

Cookies are text files retained on computers by browsers containing various information in regards to a specific website visit. Another way to think of this is that a cookie is a message given to a web browser from a web server that is then sent back to the web server whenever the browser requests a page from it.

Please note that there is a Browser imposed cookie restriction on the number and size of cookies e.g. IE 50 cookies max, 5117 characters per cookie. If this is exceeded then an error message will be displayed. The way to avoid this message is to reduce the number of Layers that are being displayed and/or reduce the number of characters used within your Layer names. |

From Version 5.4.22 and Version 5.6.26 please ignore the Expires column in the following table. From these versions of iShare Maps, cookie expiry is configurable by the iShare administrator in iShare Studio as a specific number of days. If expiry is set to 0 days, the cookies are then Session Cookies. Session cookies- are temporary and erased when you close your browserat the end of your session. The next time you visit that particular site it will not recognise you and will treat you as a completely new visitor as there is nothing in your browser to let the site know that you have visited before. |
The following is a list of cookies used by iShare Maps for each installation.
