關于Chrome支援http header最大長度限制的讨論

我們在前端通路ABAP的server的時候，通過OData協定通路一個API的時候，URL中能不能帶單引号呢？ 我們遇到一個bug，

(1) 在IE裡url帶了單引号：

https://jerry.neo.ondemand.com/dps/odata.svc/Context?KaTeX

parse error: Expected 'EOF', got '&' at position 14: orderby=title&̲filter=appUrl%20eq%20%‘CustomerEngagementCenter’%20and%20product%20eq%20’SAP_HYBRIS_CLOUD’%20and%20version%20eq%20’1611’%20and%20(system%20eq%20null%20or%20system%20eq%20’’)%20and%20locale%20eq%20’en-US’

(2) 在Chrome沒有單引号:

parse error: Expected 'EOF', got '&' at position 14: orderby=title&̲filter=appUrl%20eq%20%27CustomerEngagementCenter%27%20and%20product%20eq%20%27SAP_HYBRIS_CLOUD%27%20and%20version%20eq%20%271611%27%20and%20(system%20eq%20null%20or%20system%20eq%20%27%27)%20and%20locale%20eq%20%27en-US%27

結果就是帶單引号的URL不能被ABAP Server處理，直接是HTTP 400錯誤。是以我想問下，是不是按照OData的協定URL裡是不能帶單引号的？

我試了下，在Chrome裡，位址欄敲’i042416’， 單引号會自動被encode成%27：
