<div>This would be a good thing. That way, if you would zoom in to a location very quickly, you would also not have to wait for mapserver to render the outer zooms first (where you clicked through quite fast), but you would get your data first and the data you don't need anymore later.<br>

<div><br></div><div>There is a situation that makes the use of MapServer not very user friendly:</div>
<div><br></div><div>An user A opens a map, activates a slow layer and drags the map around. This would add a lot of calls to the webserver that would launch many MapServer processes reaching the maximum number of processes. At the same time, there is another user B displaying another layer... this time a fast layer.... As the maximum number of processes has been reached, the webserver cannot create new processes until those alive finish their work, it cannot serve the other user... that is very annoying as The other user would have to wait a long time until the queue is processed and his map is displayed. </div>
<div><br></div><div>Another similar situation is when the user A get annoyed as the map is not displaying and therefore decides to turn off the layer and turn on a different layer... say a fast layer... he still need to wait that all the MapServer processes finish the processing... That annoys the users that doesn't understand what is going on... and thinks that the server has crashed...</div>
<div><br></div><div>Is there anyway to configure Apache/Lighttpd to give higher priority to the new calls ? (that means to conver the queue from FIFO to LIFO....)</div><div><br></div><div>I have configured Apache FastCgi to kill the old processes once a minute... but the process wont die... actually they would not die with a simple kill... they would die with only kill -9 !!!</div>
<div><br></div><div>Any other solutions ?<br></div><div><br></div><div>Thanks <br>-- <br>Sebastian E. Ovide<br><br><br><br><br>
