Azure Blob CORS setup for multiple certain hosts -


the limitations configure cors in blob storages frustrating me.

  • maximum 265 characters
  • no wildcard hosts
  • maximum 5 cors rules

as result of these restrictions, come maximum of ~48 hosts.

see docs.microsoft.com.

for scenario (private cdn serve assets js, css, fonts), can not see other way use * allowedorigins. is way? nobody (no other host) should able use licensed fonts (https://www.viget.com/articles/cors-youre-doing-it-wrong).

integration

a wildcard *.int.any.local.network solution.

staging

a wildcard *.qs.any.dmz.network solution.

http://brand-at.qs.any.dmz.network http://brand-be.qs.any.dmz.network http://brand-bg.qs.any.dmz.network http://brand-ca.qs.any.dmz.network http://brand-ch.qs.any.dmz.network http://brand-cn.qs.any.dmz.network http://brand-tr.qs.any.dmz.network http://brand-cz.qs.any.dmz.network http://brand-de.qs.any.dmz.network http://brand-dk.qs.any.dmz.network http://brand-es.qs.any.dmz.network http://brand-fi.qs.any.dmz.network http://brand-fr.qs.any.dmz.network http://brand-co.uk.qs.any.dmz.network http://brand-hu.qs.any.dmz.network http://brand-ie.qs.any.dmz.network http://brand-it.qs.any.dmz.network http://brand-nl.qs.any.dmz.network http://brand-pl.qs.any.dmz.network http://brand-pt.qs.any.dmz.network http://brand-ro.qs.any.dmz.network http://brand-ru.qs.any.dmz.network http://brand-se.qs.any.dmz.network http://brand-sk.qs.any.dmz.network http://brand-tr.qs.any.dmz.network http://brand-us.qs.any.dmz.network http://brand-za.qs.any.dmz.network

live

all live host must added. no wildcard save here.

http://www.brand.at http://www.brand.be http://www.brand.bg http://www.brand.ca http://www.brand.ch http://www.brand.cn http://www.brand.tr http://www.brand.cz http://www.brand.de http://www.brand.dk http://www.brand.es http://www.brand.fi http://www.brand.fr http://www.brand.co.uk http://www.brand.hu http://www.brand.ie http://www.brand.it http://www.brand.nl http://www.brand.pl http://www.brand.pt http://www.brand.ro http://www.brand.ru http://www.brand.se http://www.brand.sk http://www.brand.tr http://www.brand.us http://www.brand.za

according rules of azure blob cors allowed origins. add 64 origin domains per cors rule. since can add 5 rules, max origin domains support azure storage 320(64*5). set origin domain following format.

http://aa.com,http://bb.com,http://cc.com

enter image description here

if origin domains count need set max 320, need use multi azure storage accounts.

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 ...
