Internet User > Internet > Mikrotik > Webserver port 8080 (static server)

I need setup webproxy on Microtik .Microtik webproxy'll work on port 80 and filter some url request for my server. Now I'm doing this with squid on same server. But I think I can do this From Microtik.

Can you give me a sample command set for this?
I want to block requests if request include "somewords" and also want block bad requests from my server.

I think I need one of nat rule. But I didn't understand from sample. I need to do a nat rule my server ip:80 > mikrotik. Microtik must work with transparent proxy for web server:8080.
How can I do this?

You want to set up a MT caching web-proxy to speed-up your web server ? And translate the service from port 8080 to port 80? And maybe to block some URL requests or URL requests that contain a certain string from getting to your web-server ?

Don't need caching. Block some URL requests or URL requests that contain a certain string from getting to your web-server.

I suppose, you need to setup transparent web-proxy, it will be invisible to router end-user.
'/ip web-proxy access' list will help you to setup filtering by content.
General information described in web-proxy documentation.

I installed weproxy service on Mikrotik, but I did'nt find how can I do content filtering with Mikrotik web proxy service. I want to do content filtering for my webserver.

I think to activate mikrotik webproxy service on port 80 with web server ip address. After do it, mikrotik'll look all web request and if request is true (some rules), I want to redirect user to my server 8080 web port.
Now I'm using mikrotik with 2 nics. First nic is for isp and other nic is for webserver. How can I do this content filter with mikrotik? Do you give me a sample command set for do this?

You want to spoof a part of a web service and make your HTTP server act as the original on some URLs ? If you replace content without the user knowing on sites that include information submitting... This is kinda illegal. Do not do it you'll get busted.
