Document Viewer

planning to resume my web base document viewer project. basically it's a PDF viewer with indexing features that load specific page by request. so it'll reduce loading time. current problem: 1. processing time. it'll take more than a minute to process/split a 8Mb pdf file. since it's web base... it will give a lot of headache. 2. uploading big file. 3. link between page... pdf will prompt 'invalid node' if link to the requested page fail.
