Can I visit a website in a script without writing to flash disk

I use the tool fetch periodically to visit a certain website in order to send some data from the mikrotik to my webserver for monitoring purposes

Even though I return an empty string from the webserver, the mikrotik is writing an empty file to the disk. Will that affect the life of the flash writes? Is there another way to visit a website without writing the result anywhere?
