regex - fastcgi_cache_key exclude some args in request uri -


my fastcgi_cache_key is: 

fastcgi_cache_key "$host$request_method$request_uri";

my $request_uri has timestamp , signature in it:

 /abc/xyz?product_id=10529125896&shop_id=17224077&shop=abc.com&path_prefix=%2fa%2fcomment&timestamp=1503044416&signature=882102c51c7b7bd4c5d8521a6565fc70c27b908547316f1123eb4af13b19f2da

so, cache miss (because has different timestamp , signature). question is:

i want create new var , use var fastcgi_cache_key. var has this:

myvar

/abc/xyz?product_id=10529125896&shop_id=17224077&shop=abc.com

fastcgi_cache_key this:

fastcgi_cache_key "$host$request_method$myvar";

how can ? much.

there 2 ways it.

if ($request_uri ~ "([^\?]*)\?(.*)timestamp=([^&]*)&?(.*)") {   set $args $2$4; } fastcgi_cache_key "$host$request_method$args";

this remove timestamp. can either modify pattern ignore 1 more field or can use twice remove field $args.

next option use openresty or nginx lua allows execute lua script in code. if conditions not considered good. having lua increases software requirement

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
