GCBridge used to encode all NGS submission information in the link to the GCBRidge validation form. Not only this sometimes resulted in very long links in the emails you received from us, but also caused bugs as the URL size browsers accept is limited (and browser dependent). With the increase in multiplexing complexity, this last point resulted in browser rejecting our links, especially when data was transferred already demulitplexed. In such situations, data transfer could simply not be performed using the usual procedure. As of today, this is no longer true as GCBridge now use another approach to transport data !
