Hey there, Thanks a lot for all you comments and remarks. I'm gonna explain somme more details. Actually, I'm using AJAX to call the php file, which will generate the molecule and display it (More or less in the way you, David, described). In this script, I put a listbox from which the user can select different molecules. Once selected, the user can visualize it by clicking a button, which calls something like disp_mol.php?name=arginine. The php file will parse it to retrieve the name of the molecule, generate it, and call it molecule.pdb (no matter the name of the molecule). Then, it loads molecule.pdb into Jmol.
As you probably understood, each molecule is not present on the server, but is generated only when the user presses the button (I'm not gonna give the reason for this because of too many details... ;) ) At this time, a new directory is created on the server (This helps me keep some traces and is easier to handle). The name of the directory is unique for each user (It is based on the IP). When a molecule is generated, it is stored in this directory. Hence, if I manually delete this directory, no molecule is present anymore. So, on the webpage, I clicked the button to display the molecule A and it appeared correcly. Then, I deleted the directory that was created. I restarted the same webpage after erasing all Internet traces (I also thought about a cache problem). I selected another molecule (B) to display and... A appeared!! Nevertheless, when I asked for viewing the molecule, B appeared (I tried under PyMol and MDL). This means that Jmol loaded well the structure, right ? The problem could come, as you, Angel and Robert, suggested, from Java cache. But, do you have any clue about how to flush it from php (or something else, without making the user manually intervene) ? Besdies this, David, the method you propose is clever and easy to set, but this can become quite heavy, in particular with large molecule. In that sense, I'm not sure this approach would be the most efficient. I'm gonna try to add a random code after the name of the molecule to download to see the result and will let you know! Thanks again.
