Hi list, Facing a difficulty here, I have the following location config: location ~\* (^/browse/$) { And this seems to catch URls like /browse/?page=35 and similar. In my understanding the $ (end of line) symbol should make this location work only for /browse/ and nothing more… or am I wrong? Thanks, Boyko ---

I need to make this location > work for /browse/ only and not for /browse/?args Add a check for $args. Something like if ($args == ‘’) { } (I don’t remember exact syntax. Please check nginx wiki for more detail) ---

Thanks Igor, Actually it was about caching - I needed to cache /browse/ only and not /browse/?stuff I used proxy\_no\_cache $args to make sure cached response wont be used when $args are present. Seems to work well, logging only MISSed responses, no cache HITs. Boyko ---

Guys, Further issue: I tried to use around 2000 pages in the same location block like this: location ~\* (^/browse|^/page2|^/page3|… etc ^/page2000) { And of-course I’m getting: nginx: [emerg] too long parameter Can I catch all these pages with a single location directive or I should separate them in different locations? Also, what is the allowed size for location parameter? Boyko ---
